How to donate blood on hgch. How to give blood on hgch? Blood test on hCG - decoding. When should this analysis be given
Chorionic gonadotropin of man (Abbreviated hCG, HGT, HCG in English, HGL in the Ukrainian language) is a hormone, which at the normal state of the body is produced exclusively during pregnancy. Hong HGG is produced after conception - it is synthesized by a fertilized egg, and after being formed trofoblast (This is the predecessor of the placenta), this hormone is produced by its tissues. That is why the level of hCG is determined only after conception.
Chorionic gonadotropin consists of two different subunits - alpha and beta . At the same time, alpha is identical to the alpha hormone subunits. When it comes to hCG - what it is, it is considered in the subunit. It is important to understand, considering what beta hCG is that this is a unique subunit, so it cannot be confused with other hormones. Speaking about the study on the chorionic gonadotropin of man, we mean that the difference between hCG and beta-hgch is missing.
What is hgch during pregnancy? Its definition and decoding is a very important stage of the diagnosis of a number of pathologies of both fetus and women. In some states that will be described in this article, the values \u200b\u200bof hCG are either strongly lowered or increased. Considering that this is for the analysis, it is necessary to consider that with small deviations from the norm of diagnostic value, this study has no. Therefore, some diseases and states of the future mother ( running pregnancy , infection of intrauterine, chronic fetoplacentar insufficiency ) Determine through other methods.
After the results were obtained, the decoding of them is carried out in the dynamics, since each woman has the level of hCG during pregnancy changes in its own way. Consequently, one result cannot be judged about the situation as a whole.
It is important that the resulting HCG analysis result for pregnancy necessarily considered a qualified specialist. After all, the decoding of the test HCG is very important, as it allows you to adjust some problems of fetal development.
Since the free beta subunit of Gonadotropin is a unique, test, where the NGH rate is determined during pregnancy, also called beta-hCG. Norma - if during pregnancy HCGB in blood appears a few days after conception. But, nevertheless, if, for example, HCG 8, which means, after the first analysis, it is impossible to say. To confirm pregnancy, you will need a re-analysis. In general, the rate of FB-HCG is a very important indicator of the development of the fetus.
Passing the hCG in Invitro, Hemotest, Helix and other clinics, you need to understand what the indicator is when the pregnancy shows such a test and others. This will be discussed in the article below.
Why do you need hgch?
Determining HCGB indicators, you need to understand what is needed by gonadotropin of a person. Wikipedia indicates the following:
- this hormone at the beginning of pregnancy stimulates the synthesis process and;
- prevents disappearance Yellow Body ;
- prevents aggression maternal organism against fetal cells;
- initiates physiological and anatomical changes in the body of a pregnant woman;
- stimulates adrenal glands and fetal glands;
- participates in the process of sexual differentiation in male fruits.
Why do this analysis appoint?
Analysis of women is prescribed with the goal:
- early diagnosis of pregnancy;
- observations in the dynamics of how pregnancy proceeds;
- definitions of malformations (anatomy of the fetus);
- development exceptions ectopic pregnancy ;
- need to appreciate whether artificially was fully carried out;
- establishing the fact that there is a threat;
- diagnostics and tumor .
Men's patients are such an analysis to diagnose tumors of testicles .
HCG level during pregnancy
The function of chorionic gonadotropin in the body is very important. Its indicators in the early deadlines begin to increase, as it produces a fertilized egg. It is hCG that makes it possible to develop, as it launches all the processes needed to carry the baby.
Already 9 days after ovulation, the hCG can be determined in blood plasma. That is, when the fertilized egg has been introduced into the endometrium, there is a slow growth of the indicators of this hormone. And if its low level is determined in the early stages, the concentration doubles every two days. What exactly should be its level at a certain week, how the HCG should grow, slow or rapid growth is noted, you can learn from the corresponding tables.
The growth of hCG during pregnancy occurs up to 8-10 weeks from the last menstruation, when its peak is noted - 500,000-10000 me / l. Further, the hormone level begins to drop, by 18-20 weeks he has already lowered half. Then the content of HCG remains stable all the period of pregnancy.
Gonadotropin during pregnancy from the body is excreted by the kidneys, therefore, it comes out with urine. It can be determined by conducting urine analysis, in the range of 30-60 days after the last menstruation. The highest rates are celebrated for 60-70 days. That is why when the CGH begins to be produced, you can make a test strip for pregnancy or other urinary tests.
HCG indicators for pregnancy in late dates can reach repeated peak indicators. Previously, such doctors considered the norm. However, it is now proved that elevated hCG in the Late time may indicate development pathology. In particular, the high hormone indicator in the last weeks of the fetal tooling sometimes means that the reaction of placenta on placental insufficiency is resh conflict .
Therefore, it is necessary to determine this disease in a timely manner and treat treatment.
The main signs of bubble drift are:
- Permanent, indomitable vomot , Much painful than in the usual one.
- Uterine bleeding (strong masses) early.
- The size of the uterus is greater than normal on this term.
- Symptoms preeclampsia (sometimes).
- Finger shakes, severe heartbeat, weight reduction (rarely).
When the signs described above are noted, it is important to turn to the gynecologist, to pass an ultrasound and pass the analysis to hCG.
If pregnancy develops normally, the indicator of this hormone rarely increases more than 500,000 me / l. There is an approximate calculation of hormone norms for each period. But if bubble skid develops, the level of hCG is different, several times exceeding these norms.
To cure bubble skid, you need to remove the entire trophoblast from the uterus. For this, scraping either other operational interventions.
May occur so that a benign bubble skid will turn into malignant chorioncarcinoma . As a rule, metastases appear very quickly with this tumor. But it is good to treat with chemotherapy .
There are the following testimony for chemotherapy:
- The HCG level is higher than 20,000 me / l month after the bubble skid was removed.
- Increasing the level of this hormone after the bubble skid was removed.
- Metastases in other organs.
Chorioncarcinoma
Chorioncarcinoma may appear both after bubble drift and after childbirth or abortion. If a woman develops this disease, then 40 days after the pregnancy ended, the level of hCG did not fall, and its increase is noted. Mineral bleeding, signs that indicate metastases can also be seen. In such a situation there are indications for chemotherapy, operational intervention. In the future, the patient should be under observation. As far as long as it should last, the doctor decides.
Application of drugs with chorionic gonadotropin
Like all human hormones, the level of human chorionic gonadotropin may depend on various factors. So, the result of the tests affects whether the woman takes the preparations containing gonadotropin of man.
As a rule, such drugs are prescribed to women with, as well as during the period when preparing for Eco to increase the hormone levels.
In rare cases, such medicines are accepted if there is a threat of miscarriage. In any case, if a woman applies such medicines, before carrying out any measurements and analyzes, you need to warn your doctor about it.
Taking a variety of drugs, many women are interested in whether they can affect the performance of this hormone. For example, they often ask whether at the level of hCG. According to experts, Duphaston may slightly influence the level of this hormone, since this drug controls the level progesterone . However, in case of non-compliance of the CCG norms, it is impossible to write it up for the influence of the medication, as it can be about pathological condition.
At the level of this hormone does not affect.
Hormonal medicines, the active component of which is the chorionic gonadotropin of a person, is funds Profhazia , Humagon , Choragon , Choriogonin , Menogon . They restore the ovulatory process, activate the hormonal activity of the yellow body. With which the size of the follicle makes the injection, the doctor defines.
Initially, studies are conducted on hormones, their norm in women and deviations. If there are certain deviations, in particular, progesterone below the norm, which this means, the doctor will explain during the consultation and prescribe a certain treatment.
If necessary, to stimulate ovulation, prescribe hCG injections from 5,000 to 10,000 me, in order to preserve pregnancy - from 1000 to 3000 meters. An individual selection of doses is important. Therefore, if an injection was carried out 10,000, when ovulation, if the injection 5000 was made, through how much ovulation, the specialist will explain.
Currently, the chorionic gonadotropin of a person is used by athletes, as under his influence in the men's organism he rises.
False positive analysis result
Those interested in what time the pregnancy is displayed for this hormone, it is necessary to consider that in some situations, tests may be false positive.
This happens in the following cases:
- Some experts argue that when taking oral contraceptives, the hormone level can increase. However, proven data about the fact that the reception of contraception affects the hCG, no.
- As a rule, after childbirth or abortion, the hormone level is reduced over seven days. In some cases, the doctor is waiting for 42 days, after which the tests occurs, and it can diagnose. If the analysis shows that HCG has not decreased or grew, then we can talk about the trophoblastic tumor.
- Level may remain elevated in the manifestation of metastases. chorioncarcinoma , bubble drift .
- Other tumors can also develop from germinal tissues, but the increase in the level of the hormone is given in rare cases. Therefore, if there is an education in the brain, the stomach, light and high level of chorionic gonadotropin, first of all, there is a suspicion of trophoblastic tumors with metastases.
Thus, the HCG indicator in non-empty should not be higher than those indicators that are normal. The rate of hCG from non-remote women - from 0 to 5. The level of not a pregnant woman of this hormone can be higher in the first days after a transferred abortion, when receiving some drugs, as well as in the development of some pathological conditions.
Immunity against hCG
In rare cases (units) in the female organism are produced to chorionic hormone. They are an obstacle for normal attachment in the uterus of a fertilized egg and its subsequent development.
Consequently, if in two or more cases, the pregnancy ended with spontaneous miscarriage, it is important to pass an analysis to the definition of antibodies to hCG and learn whether there are certain deviations. If the result is positive, for the first trimester, treatment is carried out.
A woman is prescribed glucocorticoids and low molecular weight heparins . However, it is important to take into account that the organisms producing antibodies to hCG are a rare phenomenon. Therefore, in the absence of pregnancy, it is necessary to initially go through all the research and eliminate the influence of other factors for female and male health.
conclusions
Thus, the analysis on hCG is a very important study during the period of tooling the baby. It is quite clear that after obtaining research results, patients have many questions. For example, why hCG is growing, but does not double how to properly decipher HCG on DPOs, etc., does Mioma affect the level of hormone and others. Everyone needs to be asked from a gynecologist, which will help to decipher the tests and give exhaustive answers to all questions.
Not in all situations manage to learn about pregnancy using the test. Before the delay it can be done by passing blood to chorionic gonadotropin of man.
Reduced it is called hong hCG. After successful implantation, the level of this hormone begins to grow every day more and higher. It is this growth that affects the emergence of the first signs of pregnancy.
In addition to identifying pregnancy, the delivery of hCG is practiced in other cases. Deviations from the norm of the level of hormone in the body can talk about the presence of a variety of parables. Also, the surrender of the analysis is appointed and women in the position to identify possible pathologies of pregnancy.
The chorionic gonadotropin of a person is formed at the initial stage of pregnancy with shells around the fetus. It affects the formation of hormones necessary for the pregnancy process. Later this feature begins to perform a placenta. Hong hong hong also helps the formation of testosterone in the fetus with the male chromosome. A certain amount of hCG is available in the body of a non-remote woman and, even men.
The analysis is made by taking blood from veins and identifying the level of hormone. Pregnancy test It acts on the same principle, however, the concentration of hormone in the blood is greater than in the urine. Therefore, the analysis is much harder than the use of the test.
When can I donate blood on hgch?
In the first weeks of pregnancy, the test may not show a positive result. In this case, the most reliable will be the analysis on hormone hgch.. To understand when the analysis can be handed out, the physiological processes occurring in the body of a woman during conception should be considered. The fertilization process occurs as a result of the merger of the sperm and egg. The conception is considered perfect, but the pregnancy is not yet complete, since the embryo is not accommodated in the region of the uterus, where he will have to be in the next 40 weeks.
From the site of conception, the embryo overcomes the distance to the uterus on average for 7-10 days. Sometimes this process reaches 12 days, and may be accomplished in 5 days. Arriving in the right place, the embryo is implanted into the endometrium, for which he has a few more days. All this time, hump hCG does not stand out in blood, since the embryo has not yet begun to obtain the necessary substances from the mother's organism. His stay at this time remains unnoticed.
As soon as impictation process There was a hump hump in blood, which increases every 24 hours. Therefore, after 10-14 days after the accomplished ovulation, it is possible to take an analysis to the level of hormone hCG.
In a non-heated woman, the indicators will be within 5. If the hormone level ranges from 5 to 25 honey / ml, the result is considered controversial. Then the re-fence of blood is shown.
When is it better to contact the clinic?
Despite the fact that the results will be productive from the very first weeks of pregnancy, experts advise the analysis after the delay. In this case, doubts about pregnancy are completely excluded. It is necessary to donate blood in the morning clock, on an empty stomach.
To confirm normal functioning of pregnancyIt is necessary to follow the growth of the hormone in the dynamics. For this, the analysis is rented several times with a periodicity of 2-3 days. It helps to eliminate the likelihood of the development of ectopic or frozen pregnancy. In addition, it is possible to prevent abortion.
If there is any risks, the level of hCG will not grow, and if it is, it is very slow. Too high hormone levels may indicate the development of multiple pregnancy.
The surrender of the analysis requires a certain preparation. The day before, remove fatty food from diet, eliminate alcohol consumption and reduce physical exercises to a minimum. Need to terminate any medical preparations not. The fact is that HCG is unique in its kind. No drug can affect the analysis. The exceptions are drugs that contain in their composition chorionic gonadotropin of man. This is possible if a woman was prescribed a hCG injection for calling ovulation.
However, the likelihood that this injection will affect the analysis result, extremely small. To donate blood for analysis after such procedures, as an ultrasound, physiotherapy or x-ray is not recommended.
What does the increased level of hormone sign?
Results that give blood test to hCG helps early diagnostics various diseases. With a healthy course of pregnancy, the high level of gonadotropin testifies to the development of multiple pregnancy. The higher the indicators from the norm, the greater the amount of fruits. But most often there are cases with the formation of double pregnancy.
With a unionless pregnancy, the increased level of hormone can lead to the appearance of strong edema, increase pressure, impaired in the work of the kidneys, weight increase.
In other situations, the high level of hormone signals:
- Diabetes mellitus (both in a pregnant woman and a non-remote woman);
- Forced reception of hormonal drugs to support the development of the fetus;
- The presence of pathological deviations (Down syndrome);
- Pronounced toxicosis;
- Specific time the HCG level is increased after an abortion or miscarriage;
- Pregnancy term for more than 40 weeks;
What does the low level of gonadotropin mean?
The decrease in the level of HCG does not affect anything good. If, in the absence of pregnancy, such a phenomenon is considered normal, then if it is presented, it may be threatened with unpleasant consequences. In any of the possible cases, it is necessary to carry out a number of manipulations to bring the hormone to normal. In case of occurrence ectopic pregnancy, cleaning is prescribed, since the embryo attached in an inappropriate place can increase in size, thereby damaging organs. This is fraught with a breakdown of pipes or ovary, which in late help threatens with a fatal outcome.
The decrease in the hormone in the blood occurs in the following cases:
- Deviations of intrauterine development;
- Threat of abortion;
- The probability of fetal death;
- Insufficient functionality of the placenta;
- Rejunction of the fetus;
Hgch with biochemical pregnancy
Biochemical pregnancy - This is the process with which almost every woman is facing in his life, not even suspecting it. In this situation, conception occurs, but pregnancy for some reason breaks up before the first day of the delay of menstruation.
Implantation in this case can, how to happen and do not take place. If the process of introducing into the uterine cavity was, the HCG begins to stand out into the blood. The analysis will show a positive result before the monthly delay. But if you need to observe this phenomenon in the dynamics, you can see that the hormone level will begin to fall. This means that pregnancy has broken, and without starting to fully develop. The woman can observe small latency of the menstrual cycle, but, as a rule, they will not last long.
Many women do not even suspect that they could be pregnant. They take a small delay for a cycle failure, which are a normal phenomenon for each woman. But women, for a long time, planning their pregnancy know that they are broken. Blood test The presence of HCG in the blood helps in this case diagnose the problem and begin its treatment. Thanks to this, many women with different diagnoses are able to get pregnant and successfully endure the child.
HCG level after abortion
In the body of a woman, the hong hong indicators can be enhanced if not so long ago she experienced spontaneous or medical abortion. When a woman loses the child, the fruit die, but his shells continue to be in the uterus, thereby highlighting Gonadotropin hormone.
During the abortion, the scraping of the uterine cavity occurs. After a while, the hormone level decreases. But there are cases when as a result of an abortion, a part of the shells has been preserved or the fruit remained alive and continued its livelihood. In the first case, prescribe repeated scraping, and in the second - there is a chance to make and give birth to a healthy child.
Dynamics of pregnancy development based on the results of analyzes for hCG.
- Our medicine obliges patients to take a lot of different analyzes to determine the state of health or unhealthy
- Several dozen years ago we were surprised by the ability of doctors going to talk about the absence / availability of pathologies or diseases
- Now with the development of Internet resources, access to the study of material related to the appointment and decoding of various tests and analyzes is open
- We can detail either superficially familiarize yourself with it and ask questions to doctors. Although the last moment they really do not like, and sometimes - annoying
What is hgch? When to do the test?
Laboratory employee studies blood on hgchChorionic gonadotropin of man, or abbreviated hCG, is a specific hormone, which is produced in the body in the presence of pathological growth of the reproductive system cells.
The most common application is the definition of the fact and the period of pregnancy. Also the test on the number of HCG will hand over women:
- to understand how the baby develops in the mob of mom develops
- with suspected tumors
- to assess the quality of the artificial interruption of pregnancy
- in the presence of threats of miscarriage
Men are prescribed analysis to determine the absence / availability of testicular tumors.
HCG consists of 2 elements:
- alpha particles
- beta particles
By the number of beta-hgch in the blood in the laboratory, the presence of pregnancy is established or vice versa - its absence.
When a woman is in an interesting position, Chorion is responsible for the production of HCG - the fetal shell. It regulates the growth and development of the future kid in the body of the mother while the placenta is formed, which these functions will take on themselves.
Chorionic gonadotropin also regulates the hormonal background of a pregnant woman. It controls and stimulates:
- development of progesterone hormones, estrogen
- the work of the yellow body in the ovaries
- the normal development of the baby in the mob of mom in the first trimester
Nausea, which urins many women at the beginning of pregnancy, is manifested due to an increase in the concentration of hCG in the body.
Chorionic gonadotropin is already detected in the blood through:
- a week after fertilization
- a couple of days after the delay of menstruation
In the urine, he manifests itself a couple of days later.
It is worth noting that all pharmacy tests for pregnancy show an increased concentration of the HCG or the lack of such.
Blood test for hCG - decoding: Table
The girl conducts blood test at the level of hCG - If you have been prescribed to pass the blood on hgch, then make it on an empty stomach in the morning
- The unit change in the level of hCG is MME / ml - a mili-mining unit for militers. In the body of non-sequential female, the index of chorionic gonadotropin ranges from 0 to 5 mm / ml
- From the moment of attaching the fetal egg to the wall of the uterus, the female organism begins to reinforced the production of chorionic gonadotropin. On average, its quantity doubles every day-three.
- This trend is preserved up to 9-11 weeks of pregnancy. Then the indicator is reduced and fixed at a particular level.
Approximately the dynamics of changes in the number of hCG in the body of a pregnant woman looks like this:
Norms hgch for weeks. Table

It should be noted that the work of the body of each particular woman is very individual, because specify the results obtained from a specialist who watches you.
CGH rate by day of conception
Blood in the syringe for analyzing HCG - Each laboratory has its own standards and standards for decoding analyzes, including hCG in the blood
- On the other hand, due to the difference in the calculation of the period of pregnancy, the differences in the obtained results of the concentration of chorionic gonadotropin obtained
- Obstetric period is always more embryonic because it is counted from the first day of the last menstruation

How grows hCG during pregnancy
The doctor records the result of HCG analysis in the card - Chorionic gonadotropin protects the embryo from the attacks of the maternal organism. The last in the first days and week perceives the first as a foreign body and tries to get rid of it, push out yourself
- Therefore, HCG affects the brain zones that depress the work of the immune system of pregnant. At the same time, this hormone takes control of the production of those substances that germin needed for prosperous development and life
- Such a responsible mission of HCG is accompanied by an increase in twice every and a half - two days in 5-7 days after conception. The doubt of doubling is preserved up to 10-11 weeks of pregnancy. After the pace is reduced to a certain mark and persists until the end of pregnancy
From the tables above, clearly seen in the numerical values \u200b\u200bof the change in the concentration of chorionic gonadotropin.
Hgch when measuring pregnancy
The girl is upset by the results of analyzes on hCG - Failure to pregnancy more often happens in the first trimester, rarely at later timing
- Due to the fact that the fruit egg remains attached to the wall of the uterus, the HCG is produced. Its concentration increases slightly until the fastener of the embryo and its output
Hgch for ectopic pregnancy
Girls take blood on hgch in the laboratory - The embryo shell with ectopic pregnancy produces hormone gonadotropin in a much smaller quantity than at normal location in the uterus
- Doubts doubling every 2-3 days you will not see. Nevertheless, the increase in the level of hCG is preserved, only significantly slow pace
- Sometimes it happens that an increase in the concentration of chorionic gonadotropin has a negative trend. That is, instead of increment, there is a clear slight decline
Hgch every day at double
snapshot twins on ultrasound - Do you keep the results of analysis on hgch in your hands and see that the indicators are heated in the 5MME / ml area? So the pregnancy has not yet come or you hurried with research
- If you compare the dynamics of changes in the chorionic gonadotropin with the table of its growth and see that for a specific week, your data is twice again, the likelihood of multiple pregnancy is high.
- Thanks to the data hCG, you can diagnose double much before ultrasound analysis
- Approximate figures change the number of HCG in the blood with multiple pregnancy, see the table below. The starting point selected the first day of the last month
Hgch after eco
The girl after Eco hopes for pregnancy If, with a natural occurrence of pregnancy, it suffices to pass several tests to the level of hCG, then after Eco, regular observations of the concentration of chorionic gonadotropin is the key to the success of the procedure and good development of pregnancy.
To implement Eco doctors use embryos:
- three-day
- five-day
- Therefore, the amount of hCG in the body of a pregnant woman is slightly different. For example, after the tripping of a three-day embryo, a hormone of pregnancy has a little big meaning than a five-day
- Tables of norms and ranges of HCG values \u200b\u200bAfter the embryos is easily found on the ECO method, you will easily find on the expanses of the Runet, as well as the doctor who carried out this procedure
- If you have successfully passed the ECO procedure, be prepared for the first two weeks to constant monitoring of your condition. As soon as the level of chorionic gonadotropin reaches 100 MME / ml, you can congratulate you on pregnancy
Video: Blood test on hgch
In order to diagnose the pregnancy on an early term, you can hand over the blood test on the HCG. This method is considered one of the most accurate. Chorionic gonadotropin - a hormone, which begins to be produced in the body of a woman immediately after implantation of a fertilized egg to the wall of the uterus.
The diagnosis of the growth of the HCG level in biological fluids allows us to talk about the occurrence of pregnancy. In rare cases, the hormone level may increase for other reasons. This is a sign of serious violations in the work of the body and requires immediate medical diagnosis and subsequent treatment.
First of all, chorionic gonadotropin can be determined in the blood. Already a few days after conception, the concentration of hormone in this biological fluid begins to rise.
The implantation of the embryo into the wall of the uterus occurs within a few days after conception. Thus, blood test on hCG can be carried out on 5-7 days after intimate proximity. If pregnancy has come, the analysis will definitely show it.
You can pass the blood on HCG in women's consultation, family planning center or in a special laboratory. The result of the analysis will be known very soon. It should be noted that this type of diagnosis is paid. The analysis can only be done if there are directions from a gynecologist.
Diagnosis of pregnancy at home
The level of chorionic gonadotropin in the urine after successful fertilization increases much slower pace than in the blood. In order for pregnancy to be diagnosed with test strips, which are sold in each pharmacy, it is necessary to analyze not earlier than 2 weeks after sexual contact.
Considering that ovulation, as a rule, occurs in the middle of the cycle, to diagnose pregnancy using standard test from the first day of menstruation delay.
The test can be done before. In many cases, the definition of pregnancy is possible after 7-10 days after conception. It should be remembered that in this case the probability of obtaining a false negative result is too large. If only one strip manifested on the test, you need to wait for the start of the menstruation delay and make the express analysis again.
The level of hCG in biological fluids will increase daily. If a woman doubts a negative result of the analysis, she can repeat it every 2-3 days.
On the eve of the delay of menstruation, the woman begins to think about the possibility of pregnancy. She is looking for various symptoms indicating its presence.
But the most reliable by way of determining pregnancy Before the delay is the delivery of blood test for hong hCG. It diagnoses an interesting position before pregnancy tests.
HCG analysis is a blood test for level detection horionic gonadotropin of man. This hormone is rapidly increasing in the feminine organism after the successful implementation of the implantation process into the uterus cavity. For the same principle, pregnancy tests also work, however, they reveal the HCG hormone level in the urine. In her, in contrast to blood, hormone enters a smaller concentration. Therefore, blood test shows pregnancy much earlier.
In addition, the HCG analysis allows you to define not only pregnancy, but also various diseases in which the hormone level rises. During pregnancy, the daily increase in the number of hormone is twice. Repeated analysis can diagnose ectopic or frozen pregnancy. It says stop or insufficient growth of hCG in blood.
When will the analysis show pregnancy?
There are situations in which women need to know about the existing pregnancy before the delay of menstruation. These include cases when pregnancy is undesirable or for its normal flow requires supporting therapy in the form progesterone-containing drugs.
The fact is that with a lack of progesterone, women planning pregnancy drink special drugs immediately after ovulation. This is necessary for the proper attachment of the embryo to the uterine cavity. 10-12 days after ovulation, it is necessary to make the analysis for the presence of hCG. In the absence of pregnancy, the woman cancels progesterone-containing drugs, thereby causing monthly. If it cancels medicines in pregnancy, it will not be able to save it. Early miscarriages will occur. Therefore, many women resort to this method of determining pregnancy.
The result can be seen after 2-3 days after implantation. As a rule, this process occurs in 7 days before delaying monthly. However, in the absence of special testimony, experts advise blood after a delay.
What time is it better to donate blood?
The blood test to the chorionic gonadotropin of a person helps to determine not only the pregnancy, but also its approximate time. To do this, you need to know the exact embryo implantation day. After it, the level of hCG begins to grow twice. If on the first day its level reaches 4 units of measurement, then the next day will result in 8. On the third day - 16. A pregnant woman is recognized if the HGG level reached a mark of 5 units of measurement.
Consequently, the analysis on the level of hCG can be handed over to the most early pregnancy. However, experts advise, in the absence of need, donate blood after a delay and preferably several times. This is necessary in order to trace the growth of the hormone in the dynamics.
How to prepare for analysis?
The delivery of any analysis implies the fulfillment of the standards of preparation for it. Their compliance contributes to obtaining the most correct result. First of all, you need to discuss with the attending physician the possibility of receiving certain medical hormonal preparations. It is necessary to remember whether the hCG injection was carried out several days before analyzing, since it could have a significant impact on the analysis result.
In addition, the following items should be taken into account:
- Blood should be handed over an empty stomach in the morning;
- If the analysis is noted not in the morning, then after the last meal must come more than 6 hours;
- It is necessary to exclude sports loads a day before the analysis;
- Behind the interpretation of the result, contact your doctor;
Blood fence is carried out by a medical personnel representative special orientation clinics. As a rule, the laboratory is directly on its territory. In rare cases, the biomaterial is sent to the nearby institution for diagnosis. Blood takes from the veins of hands, pre-impose on it harness. During blood intake, short-term discomfort and needle gains can be observed.
After taking the analysis, the hand must be in a bent state for some time to stop the blood. After a few minutes, unpleasant sensations and bleeding disappear completely.
Possible complications after blood fence
The likelihood that blood test to the level of hCG will result in complications, very small. The most common phenomenon is the formation of a bruise at the point of puncture. This is possible unprofessional blood fence Or, if the patient pulled his hand. A better phenomenon is considered to be a phlebitis. It is characterized by an excessive swelling of veins, which can bring some discomfort. Warm compresses should be used to get rid of the phlebitis.
With reduced blood clotting, bleeding is possible. If there is a tendency to them, you should warn a laboratory instrument in advance. Even if such a tendency is not observed, the admission of anticoagulants may affect the appearance of bleeding. This is also needed to say a nurse producing blood fence.
What does the deviation from the rate of hCG during pregnancy?
At each stage of pregnancy there is a specific level of the HCG level. Deviations from her have a number of reasons. Increased hCG Does not always indicate the development of pathology. It can talk about incorrect status of the situation or multiple pregnancy. In exceptional cases, it may be discussed by the child's Down syndrome. For a more accurate diagnosis, additional analyzes are assigned in this case.
If the woman is pregnant double, the level of hCG exceeds the norm at times, if the triple, then the indicators will be even higher. The deviation of HCG from the norm in the direction of the decrease is a negative symptom. When it is discovered, it is necessary to trace the dynamics of the hormone increase and only after that draw conclusions.
The reason for lowering the hormone can serve poorly developing or frozen pregnancy. In some cases, the slow growth of HCG speaks of ectopic pregnancy.
For the reliability of the diagnosis should be diagnosed with the help of the Uzi apparatus.
What is a triple test?
Analysis of the determination of the level of hCG in the blood can be assigned not only for diagnosis of pregnancy And when it is explicit. There is a test that is called - triple. It shows the likelihood of abnormal fetus development. In addition to Down syndrome, other diseases are determined. For example, the pathology of the nervous tube, Schoschavsky-Turner syndrome or defects of the development of various livelihood systems. However, the test result is erroneous. Therefore, even with a negative result, you should not fall into despair.
The triple test, in addition to the level of hCG, also identifies the amount of Yez and AFP. The first indicator denotes the level of the estriol hormone performing the role of pregnancy conservation. AFP is a protein that is formed in the liver of the fetus and stands out in maternal blood. Based on the total results, and conclusions are made about the possible presence of pathology.
In case of suspicion development Anomalies Additionally, ultrasound diagnostics, blood test and a fence of ammunition waters are carried out. The treatment in this case should be engaged in genetics.
In no case should not be diagnosed independently and carry out therapeutic therapy. In addition, cases of false positive result are often found. It is able to influence the incorrect definition of the period of pregnancy or the presence of pregnant diabetes.
The cost of analysis
In various medical institutions of paid services, the cost of HCG analysis may vary. Of great importance is the city in which the clinic is located. In the northern part of Russia, prices are usually an order of magnitude higher. But on average, the price of analysis varies between 600 to 800 rubles. With a re-fence of blood, the price doubles.
