Is it possible to determine pregnancy on the general blood test. Blood test for the definition of pregnancy in early terms: what is called when it is carried out? Blood from Vienna shows pregnancy

There are many ways to confirm pregnancy - from folk methods to tests sold in each pharmacy. However, their authenticity in the early deadlines is doubtful, the exact answer gives blood test to the level of the HCH - the human chorionic gonadotropin, which is called a hormone of pregnancy.

Blood changes during pregnancy

Chorionic gonadotropin of man

Hong HGG is produced by special cells of chorion - embryo shell attached to the uterus wall. It consists of 2 units:

alpha HCH - has a similar structure with components of other hormones, for example, thyrotropic (TSH), follicle-sucking (FSH), luteinizing (LH);
beta-hpch. - A unique unit is crucial in diagnosis.

The levels of this hormone in the blood are important throughout the entire period of navigation - with their help, they diagnose ectopic pregnancy and tumors, determine multipleness, recognize malformations of the fetus.

Total blood test indicators

At later pregnancy, other changes in blood components are observed:

Erythrocytes - Red blood tales, their amount during pregnancy grows by 20-30%. Normal is the indicators above 3.5 billion in a blood litter (3.5 * 10 9 / l).
Hematokritis - the volume of red blood cells in the liquid part of the blood, the increase in the level of plasma. On average, the plasma amount rises by 50%, and the erythrocytes is only a quarter, therefore hematocrit decreases from 0.34-0.36 to 0.30-0.32 (30-32%).
Hemoglobin - protein in the composition of red blood cells, which is responsible for transporting oxygen to tissues. Pregnant women develop hemodilution when blood is divorced by plasma, because of this, the hemoglobin concentration is also reduced and is 110-120 grams per 1 liter of blood.
Leukocytes - White blood cells protecting the body from pathogenic agents. The increase in their level is considered a variety of norms and is often associated with stress (for pregnancy) with blood formation. Leukocyte rate - up to 15 billion per 1 liter of blood (15 * 10 9 / l).
Thrombocytes - Blood components that are responsible for the speedy healing of damaged tissues. Their level during pregnancy can slightly decrease and make up 100-400 billion in 1 liter of blood (100-400 * 10 9 / l).
Erythrocyte sedimentation rate (EE) - Indicator of blood separation in the capillary on plasma and red blood cells. Since there is a change in the qualitative composition of blood proteins, this indicator increases to 30-40 millimeters per hour.

When will show

The chorionic gonadotropin of a person is measured in millies per milliliter of blood (honey / ml). Some laboratories measure this hormone in milli-magazine units per milliliter (MME / ml) or nanograms per milliliter (NG / ml).

The ratio of these indicators is the following:

1 honey / ml is 1 MME / ml;
1 honey / ml is 21.28 ng / ml.

Blood research allows you to determine the pregnancy in early terms - already on 6-8 days after fertilization test for hCG will be positive. In no pregnant women, the level of this hormone does not exceed 5 billion in 1 millilitress of blood, in the first-second week of pregnancy, this figure is 20-300 millions, it can grow to 4800 millions in the second third.

The work of the test strips to determine pregnancy is also based on the study of the number of HCG in the morning urine. However, the concentration of this hormone in the urine is growing much slower, therefore a reliable test result is possible only at later deadlines - 2-3 weeks after conception.

Analysis for pregnancy

Perform a reliable result will help compliance with some rules:

For the study it is required to pass blood from the vein.
Blood fence is made in the morning, an empty stomach, not less than 8 hours after the last meal.
On the eve of testing, you should refrain from active exercise, eliminate psycho-emotional loads.
If the analysis is carried out before the menstruation delay, it is desirable to take blood 2 times with a period of 2-3 days.
The result may affect the reception of medicines, in particular - hormonal drugs. They necessarily need to warn the doctor.
The processing of analysis takes 1-2 days.

Why do you need analyzes in early pregnancy

The optimal period of registration is 6-8 weeks. Future mothers often complain about a huge list of analyzes in early pregnancy.

In fact, everything is provided: in the 1st trimester, all the systems and the kid organs are laid, it becomes clear how pregnancy will occur. The slightest deviation from the norm can lead to the birth of an unhealthy child or interruption of pregnancy. Therefore, the task of the doctor to assess the risks and prevent complications.

What tests pass in the early pregnancy?

If there is an assumption that conception occurred, it is necessary to pass the analysis for the definition of pregnancy in the early stages. This will allow the girl to adjust the lifestyle, because the first weeks of pregnancy are very important for the full development of the future fetus. A doctor-gynecologist has a future mother who will find out and what tests are handed over in early pregnancy. There are many of them, but it is impossible to neglect any analysis. After all, each in its own way diagnoses the state of health pregnant.

What we do

For what is needed

Visual inspection

The doctor is obliged to measure your height and weight, sizes of the pelvis. These indicators are necessary in order for pregnancy to estimate weight gain (it should not exceed 12-15 kg for the entire pregnancy), and the ability to give birth to natural way. Too narrow pelvis may not allow it to do. The doctor will measure blood pressure, will appreciate the work of the heart and lungs.

Gynecological examination

The gynecologist examines the cervix, determines its size and shape, takes a standard gynecological smear on the flora and cytological scraping from the cervix. Gynecological smear will show the state of the microflora vagina. If there are symptoms of the disease, such as thrush, may require treatment. Cytological scraping is needed to eliminate the oncological disease of the cervix. It is extremely rare, but there are cases when an oncological disease is detected at this stage.

Ultrasound The first ultrasound is usually appointed for a period of 6 weeks. At this time, you can see the presence of a fetal egg in the uterus, the place of its fixation, and sometimes the heartbeat of the fetus. However, if the doctor did not hear a baby's heart, you can not worry - most likely it will appear a few weeks later.

Common blood and urine tests

The future mother among other studies will have to take blood test for pregnancy in early time. In general blood test, the level of hemoglobin and erythrocytes is important (with a lack of anemia), leukocytes and soe (high level can talk about inflammation). The analysis of urine for pregnancy in early time is important. The overall analysis of urine shows the state of the kidneys: if protein, sugar or leukocytes, bacteria, uric acid crystals are found in the overall analysis of urine, is a more in-depth examination. These indicators may talk about pyelonephritis, urolithiasis or systemic disease.

Biochemical analysis

We are necessary in order to assess the condition of the liver (Alt, Ast, alkaline phosphatase, bilirubin, fatty acids), pancreas (amylase), kidneys (creatinine, urine acid) and some metabolism (blood sugar, iron). If these organs need support, then the earlier it is necessary to appoint it, the most likely that everything will be fine with the mother and the baby.

Studying blood on syphilis, hepatitis and HIV among tests during pregnancy, what should be passed. This one is one of the most important. The study is necessary to reveal these diseases at an early stage when you can prevent infection of the fetus.

Study of blood at bargaining infections (rubella, toxoplasmosis, cytomegalovirus, herpes infection and other infections, such as chlamydia)

Even if you did this analysis at the planning stage, you will most likely prescribe it again. These infections are very dangerous for developing fetus.

Blood group and rhesus factor

Other studies from specialists

In addition to the gynecologist, the future mother will be necessary to visit the therapist, surgeon, ENT doctor, ophthalmologist, but if she has other chronic diseases that can exacerbate during pregnancy, then this list can expand.

Screening of the first trimester (ultrasound, HCG analysis, RARR-A)

Screening of the first trimester completes this period of pregnancy and is appointed for a period of 10-12 weeks. It consists of several tests:

Ultrasound, according to which the doctor can appreciate whether the fetus has a visually coarse development pathology, as well as the presence or absence of signs that can talk about genetic disease (Down syndrome, Edwards Syndrome);

Rarr-A or plasma protein A associated with pregnancy. This is a protein that grows progressively with an increase in the period of pregnancy. If the amount of this protein becomes less than the norm - there is a risk of genetic pathology.

Analyzes for hormones

Analyzes on hormones in early pregnancy is important to take to determine the level of human chorionic gonadotropin (HCG). Low hCG - a sign of ectopic pregnancy, underdeveloped pregnancy, threats of interrupts, as well as in chronic lack of placenta function. Increased hCG is characteristic of multiple pregnancy, diabetes sugar, early toxicosis, pathology in the development of the fetus, placental tissue tumors.

Analysis on progesterone

An analysis of progesterone in the early period of pregnancy allows you to identify the very fact of conception. After all, after that its level in the body of the girl begins to grow. However, if progesterone is above the norm, a similar result gives reason to assume that there are problems with the female genital system. Progesterone deficit during pregnancy can lead to its interruption.

One of the most frequently used methods for determining pregnancy is a pharmacy test with the corresponding functions - it is inexpensive and extremely easy to use, but not always effective. The principle of action of such tests is based on the establishment of an increase in the concentration of human chorionic gonadotropin - it is when contacting it on an indication material that the "second strip" appears on the indication material.

Along with this, the level of hCG can increase under other circumstances, for example, during the reception of some hormonal drugs. That is why a woman suspecting pregnancy for confirmation or refutation of this fact should be either under the ultrasound, or to pass the blood test in the early terms. The second option is notable for the fact that its results can be believed already 10-14 days after presumptive fertilization.

Next, you are invited to familiarize yourself with the basic information about the analysis of blood for pregnancy and other laboratory studies that a woman must be asked in early time.

The female organism begins to actively produce hCG immediately after fixing the fertilized egg in the uterine cavity, i.e. After the actual occurrence of pregnancy. Control of the level of the hormone under consideration is one of the most important studies, because In accordance with the indicators of this analysis, a specialist can judge the course of pregnancy, to timely detect the existing deviations and take action to eliminate them.

Chorionic gonadotropin of a person consists of alpha and beta subunits. In determining the fact of pregnancy, an indicator of the content of the latter is taken into account, i.e. Beta-hgch. On average, pregnant women have a two-time increase in the concentration of the mentioned hormone in the blood with a 2-3-day interval. The peak of the hormone generation falls about 8-11 weeks of terms, after which its level in the body decreases.

Important! To increase the level of hCG in non-remote women, in addition to some drugs, it can cause tumor neoplasms in the lungs, ovaries, organs of the gastrointestinal tract, the uterus, kidneys. Also, the concentration of hormone increases after a newly transferred abortion. That is why a specialist after studying the results of the study necessarily assigns other procedures to a woman to determine pregnancy (ultrasound). If during ultrasound research will be refuted by the fact of pregnancy, the doctor will take further necessary measures in accordance with the terms of the specific situation.

The first HCH analysis is appropriate to take 10-12 days after the alleged conception, or on the 4-5 day of the menstruation delay. In general, the presence of this hormone in the body is determined already a week after fertilization, but with less accuracy. That is why experts recommend women to take such an analysis at least 3 times with 2 days of periodicity - a similar order allows you to get the most accurate results.

Blood for analysis is best to hand over in the morning and on an empty stomach or during the day, but not earlier than 5-6 hours after the last meal. During the day, physical expenditures should be excluded for blood. In the case of receiving hormonal and any other drugs, it is necessary to notify the doctor to notify the doctor who will deal with deciphering analysis - some drugs distort the research results.

Important! If desired, having received the results of the analysis, you can independently compare them with the normal values \u200b\u200bset to a specialist. In this case, use the table represented by the laboratory that completed your analysis - in different clinics, the unit of measurement and normal indicators may differ, be sure to take into account this moment and do not worry ahead of time.

Other blood tests

After confirming the fact of pregnancy, the doctor will prescribe additional blood tests necessary for the registration of a woman. In the course of the research, the patient's body's body will be checked as a whole, it is eliminated or confirmed by the presence of various inflammation, infections and other ailments, the state of the fetus, etc. is estimated. A list of basic analyzes with related explanations is given in the following table.

Table. Blood tests for pregnant women

Analysis	Description
General analysis	According to the results of the study, the specialist comes to the conclusion about the presence of inflammatory diseases, the main evidence of the presence of which in this case is the displacement of the leukocyte formula. Blood is most often taken from the finger, in the morning and an empty stomach. Additionally, the content of blood platelets is determined, according to which the specialist estimates the state of the coagulation system. The level of erythrocytes, hemoglobin, as well as the color indicator for the purpose of diagnosing anemia is checked.
HIV test and different forms of hepatitis	For the study, venous blood is closed.
Blood chemistry	It is necessarily assigned when making accounting and during the period of pregnancy - usually on the 18th, as well as the 30th week of time. Biochemistry allows the specialist to assess the condition of carbohydrate, protein and lipid metabolic processes. For testing used venous blood. It is necessarily determined by the concentration of sugar and a common protein. With low hemoglobin, research is additionally carried out on whey iron, allowing to diagnose anemia. For women with chronic diseases, additional biochemical analyzes are prescribed. In such situations, specific studies and procedure for their implementation defines a specialist, taking into account the individual characteristics of the patient's condition.
Analyzes on the state of the coagulation system	The patient gives blood to the coagulogram. Additionally, the time is checked during which blood is coagulated and blood clots are formed. During such studies, the patient's tendency to bleeding is established, as a result of which the specialist concludes about the risks of pregnancy interruption (miscarriage) and additional negative points. Normally, pregnant women have an increase in the coagulation indicators - their body is configured to the upcoming delivery.
Blood band tests	Checking the blood to the group and the rhesus factor is performed, even if the woman is already known to this information. Patients with negative rear doctors usually belong to the risk group and prescribe additional research to check the content of rear antibodies.
Torch infection tests	Diagnostics of rubella, herpes and a number of other diseases are performed. So, for example, if the patient detects high LG M, this indicates an acute flow of Torch infection that requires immediate treatment. With the high LG G, it is established that earlier the patient had to meet with the diseases under consideration and the body developed natural immunity to them.
Analyzes for the genetic pathology of the child	Traditionally, on the 8-9th weeks, the women's term will receive a direction for the analysis of the analysis, according to the results of which the content of the placental globulin is determined, it is also pap-protein. Having studied the data obtained, the specialist concludes about the presence of pathologies of the fetus development and, if necessary, suggests the abortion of pregnancy to think over the patient.
Analyzes for hormones	Studies of venous blood for the content of genital hormones are performed.
Analyzes on thyroid hormones	The function of the corresponding organ of the patient is checked.
Diseases analyzes transmitted during sexual contacts	Traditionally, the blood of pregnant women is checked for the presence of pathogens of various STDs: Gonokokkov, Chlamydia, Trichomonas, Ureoplasm, Mycoplasm.
Analysis on antiphospholipid syndrome	The material (venous blood) is checked for the presence of cardiolipin antibodies and antibodies to phospholipids. If before pregnant was noted, miscarriages were noted due to the mentioned syndrome, the control of the antibody content will allow the doctor in a timely manner to take the necessary actions to preserve pregnancy.

Thus, a pregnant woman has to regularly donate blood on a different kind of research. But this does not mean that specifically in your case will need to go through all the tests discussed above: the decision on the feasibility and the need for certain inspections always remains for the doctor. The specialist assesses the individual characteristics of the situation, on the basis of which the patient gives personal instructions.

Hong HGG is produced by special cells of chorion - embryo shell attached to the uterus wall. It consists of 2 units:

Every woman wants to learn about the occurrence of pregnancy as early as possible. Modern test strips allow it to be done before delaying the beginning of the menstrual cycle, but their results are not always reliable. Therefore, women are looking for other ways to learn about their position. Many of them are interested in the question: how to determine the pregnancy in the analysis of the blood?

Some women believe that it is possible to determine pregnancy for any biological fluid, but it is not quite so. The overall blood test in this matter is not informative. Blood changes in the capillaries occur only in late pregnancy. Only in the 3rd trimester can be seen:

The number of erythrocytes during pregnancy grows by 20-30%, the indicator is considered to be 3.5 billion / l.
Changes are also exposed to hematocrit, since the volume of plasma grows by 50%, and the indicators of the erythrocytes are lagging behind. Because of this, hematocrites drops to 0.3-0.32, which is (30-32%).
Normal hemoglobin indicators for pregnant women - 110-120 g / l.
During pregnancy, the body is engaged in blood formation in stressful conditions, which is why the number of leukocytes grows up to 15 billion / l.
The level of platelets during the nipping of the child is slightly reduced to 100-400 billion / l.
ESO (the rate of embedding the erythrocytes in the sediment) increases, since the number of proteins in the blood increases. The norm is considered to be the indicator - 30-40 mm / h.

A similar pattern is sometimes observed in other deviations in the work of the body. No doctor can only put a pregnancy on the basis of these general analysis. For this, he is not enough, he does not see information about changing the hormonal background.

The principle of operation of all test strips is based on the features of the "hormone of pregnancy" - the human chorionic gonadotropin. It is able to stand out in the urine, it is at him that there is a reagent that is in the composition of all test strips. The same hormone is present in venous blood, its presence can be defined in the early time. It appears in the blood after 6-8 days after successful fertilization. There are two options for this component:

alpha HCG - this hormone is quite difficult to distinguish in composition from LG, FSH or TSH (they are determined when deciphering the biochemistry);
beta-hCG - plays a more important role in determining pregnancy.

With the help of this hormone, you can monitor the development of the fetus throughout the entire period of its toaling, it also allows you to detect deviations and pathology.

To get a reliable result, you need to adhere to a specific procedure for preparing for a blood collection:

contact the laboratory in the morning, the stomach must be empty;
since the last meal, 8 hours passed;
on the eve of blood delivery to study, refrain from physical exertion and situations that can make you attend;
if you take hormonal drugs, ask for a corresponding mark in the form.

In the state clinic for the processing of results, it takes up to 2 days, and in a private - the study is carried out in just a few hours. If you pass the blood before you delay menstruation, then you need to spend two material fences, with an interval of 2-3 days. This will make it possible to look at the hormone indicators beta-hCG in the dynamics. Hormone level can Fall, if the embryo does not attached to the wall of the uterus (such a pregnancy is called biochemical, that is, visible only according to the results of blood studies). If the level of hCG has grown, the embryo has already begun to develop.

In women who are not in the state of waiting for a child, beta-hCG in the blood is not detected, or its value does not exceed 5 MME / ml. If pregnancy has come, then you can see the increase in the number of hormone in geometric progression:

for 1-2 week after conception, the amount of beta-hCG is 20-300 MME / ml;
on 3-4 week, the value will be more than 4800 MME / ml;
fall the hormone level starts only in the 3rd trimester.

The specified values \u200b\u200bwill be fair for all laboratories, as there are several methods of blood research. Usually in private clinics when deciphering the result, food, what week after conception is the resulting HCG level.

If pregnancy was confirmed, but the amount of beta-hCG is below the minimum border, then this may be due to:

an ectopic arrangement of the embryo;
threat of miscarriage;
delay in the development of the fetus;
incorrectly defined date of conception, total with irregular monthly;
edwards syndrome;
rejunction of the fetus;
chronic placental insufficiency.

If the level of hCG is higher than the rules, then this indicates:

multiple pregnancy;
down syndrome;
toxicosis;
non-compliance of deadlines defined by menstruation with real;
enhancing blood sugar, diabetes in pregnant women.

If pregnancy has not been confirmed, and the blood hormone is found, it can become a symptom: pathologies of the reproductive system, oncological defeat of the gastrointestinal bodies and other diseases.

Is it possible to determine the pregnancy in early blood on the blood test - the procedure for holding and deciphering the study

Throughout the period of pregnancy, future mothers are advised to pass a lot of analyzes necessary in order to conduct dynamic observation of their own health and a growing baby.

Blood Analysis is the most common type of study, thanks to which the fetus is conceived, determine its age, level of development, presence of pathologies of pregnancy.

Blood is the most important health status indicator. Her regular surrender during the child's waiting allows you to determine any changes in systems and organs, as well as fix the fetal conception and the beginning of a new life in the mother's body.

Blood analysis for pregnancy is the most informative and sure way to establish the fact of conception of the child. Pharmacy Express tests used at home, even with high sensitivity to the human chorionic gonadotropin produced by the female organism (HCG), possess a large fraction of the error, leaving a chance to get an erroneous result.

You can donate blood for pregnancy for the sixth day after the expected date of conception. He accurately confirms the presence of an embryo in the uterine cavity long before in the body the hong hong level will increase so that the express test can "fix it.

This test is assigned not only to confirm the beginning of the "interesting situation", but also in order to eliminate the likelihood of the development of the baby outside the uterus and early development pathology. Also, this study allows you to establish the accurate age of the developing fetus.

If a woman knows the date of conception of a baby, she can visit the laboratory for putting the material a week. If there is no accurate data on the date of conception about the future mother, it is possible to do this during the first week after the monthly delay. At the very beginning of its development, after the attachment of the germinal egg to the wall of the uterus, the amount of chorionic gonadotropin in the human body doubles every day.

If the conception has come, it will show the level of hCG. Such a study allows you to establish the age of the fetus not only in weeks, but also in the days. This information, as well as the data on the development of the baby, obtained by ultrasound diagnostics, allow you to maximally establish the estimated date of delivery.

For research, the material takes from Vienna. The process of fence material takes a few seconds and does not threaten the health of mom and baby.

This procedure is carried out at the beginning of the first trimester, from the first weeks of menstruation delay to confirm the fact of fertilization. If a woman trusts the express test, does not plan to interrupt pregnancy and feels well, with a campaign to the laboratory, you can climb a little.

When registering a woman necessarily gives:

OAK (from the finger);
blood chemistry;
coagulogram;
material on HIV infection;
blood for hepatitis B and C;
detection of antibodies to syphilis;
inspection on sexually transmitted infections.

In addition to compulsory research, an additionally, the future mother may pass an analysis on hCG.

It is necessary if:

the doctor suspects a woman's ectopic development of the fetus;
if multiple pregnancy is installed;
the age of a woman is older than 35 years old and she in the risk of the risk of determining the child's Dauna syndrome;
a history of pregnant woman has hereditary diseases (Down syndrome, Edwards);
there is a risk of disintegration of the fetus or frozen pregnancy;
the future mother was exposed to radiation.

In the absence of these testimony, you can check the HCG level on a period of 12-14 weeks, or in the 2nd trimester for 15-17 weeks to confirm the normal development of the baby and the absence of pathologies. This is called a triple deployed test and determines not only the level of gonadotropin, but also AFP and Estor.

Another important study appointed to the woman during pregnancy is the definition of Torch infections (cytomegalovirus, rubella, herpes, toxoplasmosis).

Rent material for research in the morning time. It is recommended to abandon breakfast, alcohol, tobacco, tea or coffee. The last meal must be in the evening, no later than 20-21 hours. To put the analysis, you need to contact the laboratory, saying the name of the study. After how much will the result, it is possible and it is possible to get it urgently, depends on the laboratory in which it is carried out.

Assist the analysis in any city, at least in Krivoy Rog, even in St. Petersburg, you can in a private laboratory. No one will forbate you contact the laboratory of the State Clinic. But often in state clinics there are large queues, so it is important not to miss the deadline for the analysis, indicated in the direction of the observing obstetrician-gynecologist.

The cost of the test depends on the level of the laboratory and the speed of the results of the result. In any case, its price is not great about its great informativeness and importance.

Decoding test results for hCG is carried out with the help of special tables in which the normal level of hormones is indicated for weeks of pregnancy. Such a table shows whether the conception has come if the study is carried out on an early period, and whether the fetus of development pathology has a test, if the test is carried out at 2-3 trimester.

Low hormone indicators say about:

probable fetal death;
stopping development, lagging behind its norms;
ectopic development of the embryonic egg;
uninstalling a child in late terms.

High performance indicate availability:

suspicion of Down syndrome at the kid;
strong toxicosis;
uninstalling child.

Decipher the results can only be a specialist from a laboratory or an obstetrician-gynecologist. Independent interpretation of data is fraught with errors. When receiving an unsatisfactory result, you should not panic. There is always a chance of an error in conducting a study, so it is prescribed again. It is desirable to re-study in the same laboratory as the first time.

Common blood test provides information on the state of the health of the woman and the baby. It shows the level of erythrocytes, leukocytes, platelets, monocytes, lymphocytes, hemoglobin, erythrocyte sedimentation rate (EE), as well as characteristics of other indicators. The erythrocyte rate for a woman who is carrying baby (3.5-5.6) ∙ 10 V 12 degrees of cells / l, but this indicator does not allow you to install whether a woman is pregnant or not.

Another important indicator is the hemoglobin level. For a woman in a "interesting position", its norm is 110 g / liter. The hemoglobin level fluctuations do not indicate the offensive of a "pregnant state".

Not visible according to the general analysis of the occurrence of conception and in terms of leukocytes. Their growth in the expectation of the child is already celebrated in the second-third trimester due to improving immunity due to the toaling of the fetus. It causes an increase in leukocytes at the beginning of an "interesting situation" the presence of vaginosis, candidiasis, cystitis, colds, inflammatory processes.

Obviously, the indicators that allow us to know the usual blood test cannot confirm whether a woman is pregnant or not.

OAK Woman during the expectation of the kid drops every month. It allows you to assess the flow of pregnancy and mother health not only in the level of hemoglobin, red blood cells, or the number of leukocytes. His task is also in determining allergies in pregnant women. Basophiles are responsible for identifying it. During allergies (or the rhinitis of pregnant women, with which many milfs face) their number increases. The growth of basophils can provoke allergies to dust, animal wool and vitamins.

Another indicator indicating the development of an allergic reaction is the amount of eosinophils.

Blood neutrophily shows the development of bacterial infection in the body, the flow of purulent processes, for example, angina, otitis, meningitis.

The lymphocytes in the blood of pregnant women indicate a decrease in the level of immunity. During the hatching of the baby, the body of the future mother is exposed to a large load causing the imminent immunity, which is reflected in the blood test.

The number of monocytes is important. These are large leukocytes, the number of which increases, if the future mother has triggered, I sick, influenza, or mononucleosis, to determine which is possible to increase lymph nodes.

Important details of this topic can be found from the video:

During the expectation of the appearance of a child to the light of a future mother, it is often necessary to donate blood from veins or fingers for different studies. All of them are important and necessary for an objective assessment of the state of its health and the flow of intrauterine development of the child.

The level of hormone of chorionic gonadotropin in the blood of a woman is the most accurate way to determine whether it is in position. HCH indicates not only the fact of the development of the embryo, but also for possible risks for the state of the growing fetus, as well as deviations from the norm.

Oak is an equally important study that allows to assess the state of the future mother in dynamics and conduct its correction if necessary.

If, once again, the doctor issued a pregnant direction to the laboratory, one should not complain about the frequency of delivery of the UAK, and even more so, ignore it.

General blood test is a study determining indicators in human biological fluid. At the moment of pregnancy, the state of the woman is followed, since many indicators change and can harm both her and the fruit. In order for the study to show the right results, it is prepared. After receiving data on the results of the overall analysis of blood during pregnancy, they are attributed to the doctor to decipher them. They are judged on the state of organs and systems.

At the reception at a specialist, women often want to know whether the overall analysis of blood will determine pregnancy. It shows the following data:

hemoglobin;
blood shaped elements (red blood cells, leukocytes, platelets);
hematokritis (volume of erythrocytes in biological fluid);
leukocyte formula (the ratio of leukocytes by type);
color indicator (the number of erythrocytes saturated with hemoglobin);
ESO (erythrocyte sedimentation rate).

Increased and decrease in indicators is observed in different states and diseases. They may influence physiological factors that pass over time. One of them is a pregnancy. Since not only it affects these formations in the blood, the doctor cannot say whether the woman is pregnant, based only on the testimony of clinical blood test. Therefore, it is not true that the overall blood test will show pregnancy before the delay.

Women are often wondering how to determine pregnancy on the general blood test. The appearance of an embryo in the body of a woman changes some indicators of general blood test.

Hemoglobin and red blood cells are reduced, as an additional circle of blood circulation through a placenta is formed. With proper nutrition, outdoor walks, the use of drug drugs, the indicators of the general blood test during pregnancy are returned to normal.
Leukocytes are rising at the beginning of pregnancy. This is due to the fact that in the body of a woman there was a fruit, which is alien for the body, as it contains DNA from the Father. Over time, the state is regulated and returns to normal.

The thrombocitantary indicator increases or decreases when pathology occurs. In a healthy pregnant woman, it is within the normal range. Soe does not change if a woman is healthy. Its increase means that the body began in an inflammatory response, which does not apply to the norm.

In order for the result of generally crystal testing of biological fluid showed correct results, it is prepared. The doctor warns a pregnant woman about the rules for passing research.

One week before testing, all drugs are canceled. Many of them change the ratios of substances in biological fluid. If a woman uses a drug, without which her health state deteriorates sharply, he warns the attending physician.
It is prohibited to use alcohol per day before the study. On the day of passing the test you can not smoke.
It is forbidden to pass research within two weeks after the use of physiopulation, radiological procedures. They change the ratios of indicators in biological fluid.
The overall analysis of blood during pregnancy is given on an empty stomach. Last eating no earlier than 8 hours before testing. After the patient woke up, she needs to immediately come to the clinical institution for surrendering research. At this time, only the use of pure non-carbonated water is allowed.
To pregnant not bad, immediately after analysis, eat food. If the patient does not suffer from gestational diabetes, it is recommended to drink sweet tea.

If the patient followed the rules for passing the study, after receiving the results, the form belongs to the doctor. He decrypts them, telling a woman about the normal or pathological condition of its body. If any indicator deviates from the norm, assign an additional examination to identify the cause.

A healthy woman does not always have indicators within the normal range. Perhaps a minor deviation, which over time returns to normal. About the pathological process they say when the indicator is changed by several units and more.

After passing the overall analysis of blood during pregnancy in early terms, a woman or attending a doctor is given a form on which the number of indicators are written. For each of them there is its own norm, depending on the trimester of pregnancy.

The fact is that my girl was on the hospital, and how the blood test passed. When the blood test was ready, the doctor therapist, according to the girl she said that she was pregnant, based on the results of the analysis. If my girlfriend is really pregnant, then the term is somewhere 1.5 - 2 weeks. Is it possible with such a small period and general blood analysis to determine pregnancy or at least suspicion of it? Best answerof course not. Even from Vienna, when they are not pregnant, hgch there (in the analysis) are not specifically looking for (they need it?))))))))))

The delay of menstruation is usually caused by pregnancy. If menstruation has not come on the expected day, then starting from the next morning to diagnose pregnancy, you can measure the temperature in the rectum. If the basal temperature (BT) stably exceeds 37 * C, this indicates a possible pregnancy. However, lower indicators are also found, especially in the threat of spontaneous interruption of pregnancy.

When menstruation delay for 1-2 days and more to determine pregnancy, you can use the test for early diagnosis of pregnancy. A test for determining pregnancy is easy to use and quite reliable. The accuracy of the answer will be higher if the studies spend 2-3 times.

Despite the external differences in tests for the diagnosis of pregnancy, the basis of their action is a reaction to a specific pregnancy hormone (chorionic gonadotropin - Xg), Which begins to be produced in the body of a woman during pregnancy, and its decay products.

More complex and at the same time, more reliable methods for determining pregnancy are based on measuring the level of hormones in the body of a woman with a laboratory in the blood test for pregnancy. You rent blood from Vienna to in-hCG (blood test for pregnancy), and after a while you get the result.

In this case, to determine pregnancy, usually the level of other, more specific pregnancy hormone - trophoblastic beta globulin, which gives more reliable information, and first of all about the estimated period of possible pregnancy. The definition of pregnancy for blood test is much more reliable, although it takes more time.

The only reliable way to determine pregnancy, in addition to the analysis of blood for pregnancy, is an ultrasound study (ultrasound) of a small pelvic organs. However, these methods can be obtained information about the presence of pregnancy and its localization since 2.5 - 3 weeks from the day of conception.

But since the start of the menstruation delay, some time passed, blood tests for pregnancy gave a positive result. Is it worth going to the gynecologist? Worth it. First of all - to make sure that the pregnancy is uterine.

Blood tests on the definition of pregnancy is equivalent to give a positive result both in uterine and ectopic pregnancy. Therefore, if there is at least the slightest doubts, make tests or blood tests to the early definition of pregnancy and at a positive result, visit your gynecologist.

In case the pregnancy test gives a negative result, and the delay of menstruation continues, visit the gynecologist - an endocrinologist to clarify the causes of the menstrual cycle.

If you want to take a pregnancy analysis from the first day of delay, make an ultrasound, get a consultation of a gynecologist's doctor, contact our medical center. The cost of analysis, including blood fence from veins - 800 rubles, the result will be on this day or the next one.

The most reliable method in the arsenal of modern medicine is determining the occurrence of pregnancy on the analysis of blood.

The method of determining pregnancy on blood test is based on determining the level of "pregnancy hormone" in the blood of a woman. Special hormone pregnancy is called the chorionic gonadotropin of man (HCG), produced by cells of a special shell of the embryo - chorion. If a chorional tissue is present - there is a pregnancy. This makes the definition of pregnancy in the early terms possible by blood test: after a week after conception, the result of the analysis by the level of hCG will be guaranteed positive. Normally, the level of hCG in the serum of a healthy non-pregnant woman is from 0 to 15 honey / ml.

In addition to determining pregnancy, this analysis is appointed to identify the pathology of the fetus (in the period from the 14th to the 18th week of pregnancy).

Make a reliable HCG analysis at any time convenient for you and even urgently you can always in the center of traditional obstetrics and family medicine.

Traditionally, the definition of pregnancy for blood test is produced on the eighth day after the alleged woman conception, but not earlier than in 3-5 days of menstruation delay. For this morning, an empty stomach, venous blood fence is made. If you are planning to pass the analysis at another time of the day, you need to abandon meals for 4-6 hours before the procedure. If you take medicinal or hormonal drugs, be sure to influence this informant of your gynecologist or nurse.

To clarify the results, the test can be repeated in a few days. More detailed recommendations for the preparation for the analysis will give you the chosen gynecologist of the center.

Hello! Tell me please, I had an unprotected sexual intercourse on March 7, after that, after 2-3 days there were frequent urge to urination, wild pains and spasms appeared during urination. I went to the gynecologist for the first day after sexual intercourse, she looked at me and said that everything was fine with the women's authorities, he sent to the urologist, he said that I had inflammation of the bladder, I passed the analysis of urine - cystitis and possibly picked up Trichomanada. Week 2 had a near abdomen, and now the second day is the delay of menstruation. Is there a chance that I got pregnant? And is it possible to learn about this for the full analysis of the urine shown just below? Thank you. Tsvet Yellow

Pregnancy is possible. It is impossible to determine it for general analysis of urine. In an early period, you can diagnose pregnancy, passing blood to beta-hgch or spending a transvaginal ultrasound.

Sincerely, Yurchenko Oksana Viktorovna.

Currently, there are several methods that allow you to quickly and accurately determine pregnancy. One of the most popular of them includes pregnancy tests sold in pharmacies. However, a more accurate result can be obtained when analyzing blood for pregnancy based on the level of hormone level HCG.

Special hormone, not produced in the body of a man and a non-embled woman, is chorionic gonadotropin, called abbreviated hCG. With the occurrence of pregnancy, the envelopes of the fetus, namely the chorion, begins the release of the specified hormonal substance. The presence of gonadotropin in the blood allows to determine the pregnancy in the analysis of blood with high accuracy.

Just for this reason, this study is called blood testing for pregnancy.

As follows from the instructions for a standard pharmaceutical test based on the presence of a chorionic hormone in the urine, it is possible to obtain a reliable result on it, not earlier than the first day of delay. It is possible to determine the pregnancy on the analysis of blood in the tenth day since fertilization, that is, about a week before the next planned menstruation. Thus, the possibility of conducting earlier diagnosis when the blood test for pregnancy and the term on which this study can be carried out are undoubted advantages of this method before the "ordinary" test from the pharmacy. However, such an analysis was created not only so that impatient parents as soon as possible recognized the desired results.

Many women are asked what the HCG indicators should be on one or another gestation. It should be noted that each of these deadlines has a fairly broad boundaries of normal values, which is not always possible to find out how well the embryo is developing. However, when surrendering blood test for pregnancy twice and more, it is almost always possible to obtain the right results. In some situations, future mothers are impossible to conduct any other surveys, except to suggest testing blood test for pregnancy, so such situations have to rely only on the results obtained from the blood test.

The unit of measuring the level of chorionic hormone is honey / ml. For men and women who are currently not waiting for the appearance of a child, the HCG indicator matters less than 5. For pregnant women, the content of this hormone is determined for each period of pregnancy separately.

Compared to the initial indicator, which makes up less than 5 honey / ml, the content of the chorionic hormone in the blood of a woman who is carrying a child will always be elevated. And in some cases, the level of this hormone increases even more than the corresponding period of pregnancy should be. A significant increase in the level of chorionic gonadotropin occurs with a multiple pregnancy of the patient. In this case, the value of this hormone can exceed 1.5-2 times and even more than the normal level of hCG for each period of pregnancy.

Such a study as a blood test for hCG should be carried out far from every case of pregnancy. If the toaching proceeds well, then there is no need to take this analysis. However, in any case, the implementation of blood test on hCG provides diagnostic information on the basis of which possible disorders in the development of the fetus can be identified, to choose the necessary treatment, and in the normal development of the child to please such information for future parents.

How to determine pregnancy on the blood test? If you have a menstrual cycle delay, it may indicate pregnancy.

This is due not only to the fact that the test is not quite qualitative, but also by the fact that in a period of up to three days of delay, the number of hormone needed may be insufficient. For the most part, this is a consequence of the individuality of the body, and not some pathological deviations. In order not to get into such an unpleasant situation, specialists are recommended to test blood for pregnancy.

Nowadays blood analysis to determine pregnantb is considered the highest quality and accurate way. Thanks to this analysis, the doctor will definitely be able to determine the number of beta hormones that are responsible for the exact definition of this issue. Such hormones are known as HCG. They appear in the body of each woman at the moment when its fertilized cell begins to share. Such a test can accurately determine pregnancy for the second day after conception.

Some girls often ask a question related to whether such an analysis can show an incorrect result. The question is pretty natural, and it is worth recognizing that such an analysis can be erroneous. But this is not connected with the fact that it is not reliable. This can only be if the girl or woman takes hong hong for treatment. It is in this case that a similar test can show pregnancy from a non-embled woman.

In order to pass the blood to a similar test, you should know some nuances. Blood should be handed over in the morning before you have taken food. If you did not have time to do it before meals, then you should wait five hours, after which the blood will be cleaned, and will be ready for analysis. Blood surrendered from Vienna. You can pass it in a clinic or female consultation. In addition, you can use the services of private examinations. This is a fairly common method, although more costly. We hope that such information will help you to save your time and nerves, which will inevitably need in case of ignorance of such nuances.

To make sure the conception occurred or not, you can analyze blood for pregnancy - the so-called HCG analysis. What it is when and how to pass it right - read further. What is hCG?

Determine the blood test pregnancy is very simple, and most importantly, this is the most reliable method, although it takes more time than the common pharmacy tests. When surrendering blood analysis on hCG, pregnancy will be determined by the presence or absence of a human chorionic gonadotropin in your blood. This hormone appears in the body of a woman at the beginning of pregnancy. When the egg is divided, the embryo and the fruit shell are formed. Chorion is one of the fetal shells. It is it that it produces hCG, which is found in the blood. The overall blood test during pregnancy is prescribed to all women without exception, but it does not show the level of hCG, blood for this analysis is collected specifically. How to properly pass the blood test on hgch?

Usually, a gynecologist tells about this, but if you have not received any recommendations, we will tell you several fundamental points. The analysis take blood from Vienna. It is advisable to come from the morning, as you need to pass the blood of an empty stomach. Be sure to inform the doctor or nurse if you accept any hormonal drugs so that the test be as objective as possible. Analysis on the definition of pregnancy can be carried out after 3-5 days of menstruation delay. Deciphering for pregnancy analysis

Passing the analysis on hCG, pregnancy can be determined in the earliest time, starting from 1 week. There are certain permissible HCG standards in the blood. In the period of 1 trimester, the level of hCG is increasing every day in two. On the 10-12 week of pregnancy, the highest level of hCG in the blood is observed. Then it remains approximately at the same level during the second half of pregnancy.

HCG can increase, if you have multiplot, toxicosis, prestal, diabetes, the pathology of the fetus or incorrectly installed the term of pregnancy. If the level of this hormone is very low, then this may be evidence of ectopic pregnancy, delays in the development of the fetus, threats of spontaneous abortion or, again, improper definition of the period of pregnancy. The correct decoding of your analysis, taking into account individual characteristics, only a competent specialist can give.

Blood test shows pregnancy, which is very convenient for its early definition, because where a simple test may not give the correct answer, the HCG analysis will not submit.

The first signs of pregnancy in the early dates are inaccurate and often mislead women. During pregnancy, menstrual-like allocations are possible. To diagnose pregnancy on time, with the slightest suspicion or presence of symptoms, contact the gynecologist. For early diagnosis of pregnancy, a gynecologist is needed to consult a gynecologist, an ultrasound and determination of the level of hCG in the blood test.

Any menstruation delay may indicate the beginning of pregnancy (even if the woman assumes that it is impossible - reliable contraceptives were taken). In some cases, the cause of the monthly delay can be:

acute or chronic inflammation of female genital organs is a strong emotional and dube other stress, overwork, change of climate, any disease Lack of ovulation in this cycle or late ovulation (consequence of hormone therapy) Functional ovarian cyst - follicular cyst of non-unreold follicle (luf syndrome) or yellow cyst Body (which can sometimes "live" longer than the usual, thus delaying the occurrence of menstruation)

Recently, the asymptomatic flow of gynecological diseases is very common, including sexually transmitted tumors. Even pathological discharge from the vagina with such diseases does not always happen. Without analyzes, it is difficult to distinguish them from normal discharge. With a hidden course of female diseases there is no pain in the abdomen, bleeding, menstrual disorders and other symptoms. Therefore, each woman at least twice a year is necessary preventive examination of the gynecologist.

To determine the individual survey program at the first signs of pregnancy, contact the gynecologists of our clinic. Determination of pregnancy when a monthly delay

Monthly Delay and Pregnancy Test Negative

When pregnancy occurs in the morning portion of urine, a pregnancy test is indicative only from the first day of the delay of menstruation. False negative test results for pregnancy in early time are more often false positive.

With a small delay of monthly pregnancy tests can give a false negative result when pregnancy occurs. This is due to the fact that the level of hong hgch at the beginning of pregnancy is still not high enough. In 5-10% of cases, an implantation during a delay of 1-2 days has not yet occurred, therefore, pregnancy tests in the early deadlines will be negative. Also the cause of a false negative test result when a monthly delay can be:

pregnancy test with an expired shelf life, or have been violated test storage rules on the eve of the pregnancy test, a large amount of liquid was discarded. For pregnancy test, stupid or not morning urine has a kidney disease

If there is a suspicion of pregnancy, and the pregnancy test is negative, you need to pass the blood test on hong.

Blood test for pregnancy hump hCG

The accuracy of blood analysis on hong hCG is higher than when used to diagnose pregnancy pregnancy tests. The first reliable sign of pregnancy is an increase in the level of hong hgch in the blood. The level of hCG in the blood during pregnancy rises much earlier than in the urine. In order to find out, you are pregnant or not, you need to hand over blood for HGG analysis. This analysis shows the presence of a human level of chorionic gonadotropin in the body of a human level is the earliest sign of pregnancy. Chorionic gonadotropin is a hormone of pregnancy. When conception occurs, the egg is divided, and in the division process develops the embryo and the fetal shells, one of which is called Chorion. It is Chorion that produces HCG, which is found in blood test. In very rare cases, hCG is present in the body of a non-pregnant woman or man. This happens in some diseases. In some cases, this hormone may be present after an abortion. The level of hCG in the body increases during pregnancy.

If the blood test on the HCG is negative, it is necessary to find out the cause of the impairment of the menstrual cycle. If the result of the analysis is dubious, it is necessary to reckon it after 48 hours. With a developing uterine pregnancy, the HCG level after 48 hours will grow by 2 times.

Blood for analyzing Hong HGG is taken from Vienna. Blood must be handed over to an empty stomach in another day. Blood can be taken at least after 4-5 hours of refraining from food. It is necessary to inform the doctor about the medications at the moment the analysis is carried out on 2-5 months of menstruation delay.

During pregnancy in terms of hCG, you can monitor the course of pregnancy. Low indicators of HCG in pregnant women can talk about pathology (ectopic pregnancy, pathology in the fetus, placental failure, etc.). HIGH CHG rates can be with multiple pregnancy, in the pathologies of the fetus.

Determination of pregnancy on ultrasound vaginal sensor

If the ultrasound results correspond to the second phase of the menstrual cycle (thick mature endometrium, the yellow body in the ovary), then the beginning of pregnancy and it is necessary to donate blood on hCG. If there are no pictures of the second phase of the menstrual cycle on the ultrasound, the pregnancy is not much likely, it is necessary to be examined to establish the cause of the delay of menstruation, which is most likely due to the violation of the ovarian function.

Pregnancy test positive

If the home test for pregnancy and the result of HCG analysis is positive, ultrasound with a vaginal sensor should still be done to learn the localization of pregnancy (uterine or ectopic) and its vitality. When the test is positive, the pregnancy is already almost always visible on the ultrasound with a vaginal sensor. Frequent ultrasound on any gestation period, including early - absolutely harmless. Extra days lived with an undiagnosed daily pregnancy in time are very dangerous.

The first signs of the start of pregnancy to the delay of monthly the first signs of the start of pregnancy before the monthly delay

The first signs of the start of pregnancy before the delay of monthly inaccurate and are often introduced to the delusion of women hoping for the onset of pregnancy or avoiding pregnancy. This is because the first signs of pregnancy before the delay of menstruation can often occur outside pregnancy. Nausea, vomiting, fatigue, headache and increasing the mammary glands are every second pregnant woman. In some women, the first signs of pregnancy appear even earlier than the delay of menstruation, but they are extremely not reliable.

The first sign of the start of pregnancy is considered to be a delay of menstruation. But many women have latency of menstruation, in no way associated with pregnancy. The reason for the delay of menstruation can be any disease and stress leading to a violation of the hormonal background. And then the first signs of pregnancy before the delay of the monthly, too, do not talk about anything.

There are such cases when a monthly menstrual bleeding is observed in the early pregnancy of pregnancy. But this is not menstruation and such a state requires the observation of the doctor. This is usually happening in those days of the month when a woman had to begin menstruation, if the pregnancy did not come. Such a pathological condition does not give on time to recognize the first signs of the start of pregnancy. Bleeding occurring in early pregnancy (if it is not a detachment of a fetal egg), often different from ordinary menstrual discharge by its number and color.

As the first sign of the start of pregnancy, it is worth perceiving the situation when a woman in the last menstruation has sharply reduced the number of discharges, whereas before the monthly was abundant. Moreover, such menstruation ends faster than usual. In the presence of an unprotected sexual intercourse (or when using low-efficient prevention tools) in the last menstrual cycle, it is possible to say with confidence in 50% that this is the first sign of the start of pregnancy. Although there are cases where menstruation is not as usual, due to some hormonal changes occurring in the body. This often happens in the first cycles of receiving combined oral contraceptives.

To make sure at the beginning of pregnancy, you can measure the basal temperature in the first half of the next menstrual cycle. Its raising is another first sign of the start of pregnancy, but not before the delay of menstruation, and after. Correctly measure the basal temperature (the temperature in the rectum) from the first time is not easy. And an inexperienced woman may admit some errors in its dimension, which is why you can see a non-existent pregnancy. If the basal temperature is raised to 37 and higher than degrees and you measured basal temperature correctly, then this can be regarded as the first sign of pregnancy.

The appearance in the blood and the urine women HCG is one of the first signs of pregnancy. HCG is deciphered as chorionic gonadotropin. This is a protein that appears in the blood and the urine of a pregnant woman, somewhere a week after fertilization. A non-heated woman has its level on the results of the analysis nearers to zero. If the HCG is present in the blood, then this is regarded as one of the first signs of the start of pregnancy.

Sometimes, false positive and false-negative results of this analysis are quite rare. The false positive result can be obtained by handing blood on hCG during the period of ovulation, high level of the hormone of FSH, tumors producing hCG, with thyrotoxicosis, hematuria, etc. A false-negative result may be when measuring pregnancy, on a very early period of pregnancy and in cases where it is examined not the morning, stumbling urine.

The reliability of blood analysis on hCG is higher than the analysis of urine on hCG. Correctly shared analysis guarantees almost 100% definition of presence (absence). You have pregnancy before or after the monthly delay. The first sign of a normally developing pregnancy can be considered a good increase in the level of hCG. Every day, after implantation of an egg to the mucous membrane of the uterus (this happens before the start of the delay of menstruation), the level of hCG is doubled every day. At later deadlines, the strong growth of HCG speaks of the presence of pathologies of the fetus. The HCG level remains at a sufficiently high level for 4 weeks after an abortion or miscarriage.

Sometimes a pregnancy test can show pregnancy and before the start of the delay of menstruation. Such a first sign of pregnancy can be identified if there is a woman early ovulation and using highly sensitive pregnancy test.

Supplementary, probable and reliable signs of pregnancy at different timing

Signs of pregnancy can be divided into presumptive, probable and reliable. Do not forget that only a gynecologist can confirm or eliminate pregnancy. The test for the definition of pregnancy is not always accurate, so at first suspicions at the beginning of pregnancy, immediately contact a specialist.

Supporting signs of pregnancy

Supporting signs of pregnancy are nonspecific and may occur in unable to other states.

Dizziness and fainting, most often in the morning - there are a symptom of vegetual-vascular dystonia, with stressful situations, nervous and physical exhaustion, anemia, reduced blood sugar content.

Nausea and vomiting is one of the signs of toxicosis of pregnant women, but the same symptoms can be observed in diseases of the gastrointestinal tract (gastritis, ulcerative disease of the stomach and duodenum, poisoning, inflammation of the gallbladder and pancreas).

Changing taste, preference products that used to be used in limited quantities (salty, sweet) can be a symptom of gastrointestinal diseases, lack of vitamins and minerals in the body, anemia.

Student urination during pregnancy - the result of pressure on the bladder of the increased uterus. But this symptom may also testify to the infection of the urinary tract: cystitis (inflammation of the bladder), pyelonephritis (kidney inflammation).

Probable signs of pregnancy

One of the first signs of pregnancy in the early time is the delay of menstruation. But the latency of menstruation besides the start of pregnancy can be observed at any hormonal disorders.

The increase and painfulness of the mammary glands at the beginning of pregnancy occurs in response to hormonal changes in the body. At the same time, changes in the mammary glands occur, they become more dense and painful, the area can darken, the nipple will increase. But the increase, soreness, the seal of the mammary glands is also noted during mastopathy.

Increasing the uterus with the softening of its carriage (symptom of the Khigar) determines the gynecologist during inspection.

Cyanosis of the walls of the vagina and cervix (sampling symptom) also defines a gynecologist.

Reliable signs of pregnancy

With 1-2 weeks of pregnancy in urine and blood, chorionic gonadotropin is determined. Tests for pregnancy are based on its identification. The definition of hong hong in the blood is a more reliable way to determine pregnancy in the early stages.

Ultrasound examination Already under the period of pregnancy, it allows you to detect a fruit egg in the uterus cavity, and from 7 to 8 weeks - the heart activity of the embryo.

The palpitation of the fetus is determined using an obstetric stethoscope (the hollow tube one end of which is applied to the belly of a pregnant woman, and the other to the doctor's ear) starting from the 16th to 8th week.

Fetal movements pregnant feels from 16-20 weeks. These sensations may be different - from barely distinguishable shocks to "turbulent activities".

The term of pregnancy can be defined in several ways:

By date of the first day of the last menstruation.

In size and uterine position. which are determined by the obstetric inspection. For example, on the 6th week, the uterus is slightly increased, for 8 weeks it reaches the size of a female fist, by 12 sizes of grapefruit. At 16, the bottom of the uterus is located 7.5 cm above the pubic bone, at week 20 - for 2 fingers below the navel, on 24 weeks the bottom of the uterus reaches the navel or 1 cm above. At 27, the bottom of the uterus is located 3 cm above the navel, 32-one 6 cm above the navel, for 40 weeks the bottom of the uterus for 4 fingers below the rib arc.

According to ultrasound. From 3 weeks you can find a fruit egg in the uterus cavity, and from 7-8 weeks the heart activity of the embryo is revealed.

According to the first movement of the fetus, which usually occurs at primordin on 18-20, in repeatedly on July 16-18.

As a rule, the pregnancy lasts 280 days, or 10 obstetric months, counting from the first day of the last menstruation. In the obstetric month 28 days or 4 weeks, respectively, the duration of pregnancy is 40 weeks. 10 obstetric months are approximately 9 calendar months. The entire period of pregnancy is divided into three trimesters: the first (1-14 weeks), the second (15-27 weeks) and the third (28-40 weeks). During the period of pregnancy from the fertilized egg, a mature fruit is developing capable of non-busing existence

Regardless of whether you are planning a child's birth or not, the delay of menstruation always causes exciting experiences in women. And the first thing that needs to be done in this case is to determine whether conception occurred, namely, to pass for pregnancy analyzes. The most common and affordable way is home express tests. But, as practice shows, the results are often inaccurate. In order not to make an infinite number of attempts, doctors recommend resorting to a more reliable way - to pass the blood test for pregnancy, as a result of which all further doubts are discarded.

What is this study? What does it show? How to determine the blood test? When and how to pass it? Let's deal with.

Laboratory testing of blood on the definition of conception is detected in the body of a woman a special hormone - human chorionic gonadotropin (HCG). It is produced by the embryo shell - chorion, and begins to stand out in the body from the first hours of fertilization of the cell. And if this hormone is present in the body - there is a conception. At the same time, its concentration in the blood of a pregnant woman doubles every two days. And its highest level reaches its level for 8-11 weeks, after which there is a decrease.

Express tests for pregnancy also determine the level of hCG, showing that the most second strip, but the concentration of this hormone in the urine is significantly lower and increases much by smaller. Therefore, a more accurate study for determining fertilization is considered to be a blood test, which is able to identify the conception of 2-5 days after fertilization. While the test strips is only a week later.

For the normal development of the fetus, the level of this hormone is very important in a woman, because it also points to the success of the growth and development of the fetus, therefore it is necessary to track it throughout the entire period of the baby tool.

Also, hong hCG helps to assume the term of pregnancy, relying on the level of its blood concentration.

It is very important to track its level throughout the entire period of the child's waiting, as it may indicate possible pathologies in the development of the fetus. The first screening is done in the period from the 11th to the 14th week of pregnancy, where the plasma protein of RARR-A is also investigated and an ultrasound of the embryo is carried out, which determines the presence of chromosomal deviations from the fetus. Research, second screening, is carried out at 16-20 weeks. The data obtained are not a final diagnosis, and only determine the risk group and appoint additional research. It should also be noted that the definition of the level of hCG is only part of the study that is not in itself reliable screening.

Deviations from the norm may appear with such serious problems as a frozen or ectopic pregnancy, the threat of breakdown (in early terms), pathology in the development of the fetus, multiplotion, etc.

The blood test to the level of hCG can already be handed over if menstruation is delayed for 3-5 days. In the case when the exact date of conception is known, in a week you can go to the laboratory to confirm or disprove the fact of conception. Be prepared to repeat the procedure at least twice in 2 days, preferably at the same time in the same laboratory, to track the growth dynamics.

Analysis in the morning on an empty stomach by fence blood from veins. If you take it in the afternoon, then on the eve I recommended to refrain from food for 4-6 hours. In the case of taking hormonal drugs, you need to prevent your doctor about it. It is also recommended to exclude heavy physical exertion, nervous shocks and physiotherapy procedures per day before visiting the laboratory.

The first thing to pay attention to when deciphering the results of laboratory studies is units of measurement. They may be as follows - honey / ml, units / lm, MME / ml, MIU / ML. Specially translate one to other need. No, this is the same thing, and there is a sign of equality between them. But on the testimony of the norm should be paid priority, since each laboratory will have their own. It depends on the sensitivity of the methods used.

It is also necessary to know that with multiple pregnancies, the HCG indicator will be increased multiple of the amount of embryos.
The level of this hormone until the 10th week grows rapidly every 7 days, after some time it stabilizes and begins to gradually decline until the moment of birth.

Tables rules hgch for weeksWidely distributed on the Internet, clearly demonstrate such a dynamics.

At the 1st week, the hormone level is small and amounts, on average, from 50 to 300 honey / ml. In the next 7 weeks, he continues to grow rapidly, reaching his peak on the 7-8th week, when the indicator of the upper limit of the norm is 200,000 honey / ml. And the next two trimesters of the child's expectation is a gradual decline of up to 10,000 - 60,000 honey / ml at the time of birth. At the same time, the date of last menstruation is taken to determine the period, and not the date of conception.

Remember - only your attending doctor can give the most reliable data decoding. Because the range of norms is wide and need to consider a number of individual factors. And some indicator for one woman may be suspicious of pathological processes, and for the other, it is completely fitted within the limits of the norm. Therefore, only a doctor who knows all the features of your body, is able to draw conclusions and assign subsequent steps.

With a laboratory study, two variants of deviation from the norm - HCG are higher and below the norm.

The low rate of this hormone in the analysis of blood for pregnancy in early terms speaks of sufficiently dangerous and pathological conditions:

hormonal failure of a woman;
ectopic pregnancy;
intrauterine fetal death;
risk of miscarriage;
pathology in the development of the embryo.

In the later dates, it may be evidence of a child's migration. In any case, the present reason determines the doctor based on additional research.

Increased HCG indicator can be with:

multiple pregnancy;
reception of hormonal drugs;
diabetes in a woman;
toxicosis;
gestosis;
the pathologies of the development of the embryo.

When obtaining results, you should not make hasty conclusions. Deviations from the norm on any part can often be caused by the incorrect definition of the period of pregnancy. And only the doctor decides on further actions. And the first thing he appoints is a re-study, because it is very important to track the level of this hormone in the dynamics. Also for further conclusions, additional diagnosis is carried out, the basis of which is ultrasound.

Like any study, the HCG analysis carries the risk of errors. Such results are called falsely negative (if the conception occurred, and the analysis did not reveal this) and false-positive (fertilization was not, and the analysis shows the opposite). The probability of the first increases on too early blood flow when the fruit egg has not yet attached to the wall of the uterus and the hormone level is too small. The reason may also be a late ovulation, an ectopic pregnancy, a sharp change in the hormonal background. False-positive results may occur when taking hormonal drugs, which include hCG, as well as serious tumor diseases.

Although it is very rare (with a probability less than 2%), erroneous analysis data is obtained when the procedure for collecting material in a laboratory, or an error in determining the term of pregnancy.

In any case, if you have doubts, consult your gynecologist and go through a number of necessary additional research.

The most simple and well-known home express tests are valid for the same principle, only reveal the level of hCG in the urine, where its concentration is significantly lower. A modern express test has sufficient sensitivity, and most often gives reliable results about the presence of conception. In addition, its availability and simplicity of use is an indisputable advantage. It is with his help most women get rid of doubts, and blood test only finally confirms the result. Therefore, these two methods perfectly complement each other.

But the greatest accuracy in determining conception gives ultrasound. Already from the 4th week of the term, the intravaginal sensor visualizes the fruit egg size of about 2 mm. And later (from the 5-6th week) makes it possible to confirm the formation of a yolk bag, attaching the embryo to the uterine cavity and the viability of the fetus. In the aggregate, the level of hCG and ultrasound make it possible to identify all possible pathologies in the early stages.

The following video describes in detail the analysis on hCG, as well as its decoding:

Many women, especially those who wish to become Mom, claim that they feel when the magical moment of conception occurs. Others notice only those changes in the body that is hard to ignore (delay of menstruation, for example). Both those and others eventually resort to modern methods of research, the first in the list of which are homework, which confirmed their effectiveness, and in 90% of cases give the correct result. But to get rid of all doubts you need to do two, or even more express analysis, and it can be in vain not to spend time and means, but immediately contact the laboratory and pass the blood test. After all, only after it you can declare "I am a future mother" with confidence.

Today, the most popular way to independently diagnose pregnancy is to buy in a pharmacy, the mechanism of action of which is based on the analysis of the Woman's urine. However, the sensitivity of the tester is rather low: resorting to the test as a single source of information about a possible "interesting situation", the woman risks being disinforced. Other homegrown methods are frivolous if not to say a dangerous path. The most reliable method in the arsenal of modern medicine is determining the occurrence of pregnancy on the analysis of blood.

In addition to determining pregnancy, this analysis is appointed to identify the pathology of the fetus (in the period from the 14th to the 18th week of pregnancy). Make a reliable HCG analysis at any time convenient for you and even urgently you can always in the center of traditional obstetrics and family medicine.

How to pass the blood test on hgch

If you take medicinal or hormonal drugs, be sure to influence this informant of your gynecologist or nurse. To clarify the results, the test can be repeated in a few days. More detailed recommendations for the preparation for the analysis will give you the chosen gynecologist of the center.
