Table of hCG in IVF

Determining the level of human chorionic gonadotropin is considered one of the most common methods of diagnosing pregnancy. Only after reaching the level of more than 1000 mIU / ml can you see the nascent life with the help of ultrasound. This hormone secretes the fetal membranes, so it has diagnostic value only during pregnancy.

Dependence of hCG and gestational age

The level of hCG during pregnancy after IVF is characterized by certain fluctuations in different periods. The following table shows the hCG during pregnancy with IVF and the characteristic increase in its level:

Consider the dynamics of hCG growth in IVF in the case of pregnancy. According to the table of hCG with IVF during the first month there is a significant increase in this indicator.

The level of hCG at ECO doubles every 36-72 hours. The maximum growth of hCG in IVF is observed approximately at 11-12 weeks of gestation. Then there is a gradual decline. But the placenta and fetal membranes continue to function, so a fairly high level of hCG is maintained. And with the premature "aging" of the placenta, the hCG values ​​with IVF decrease more quickly. Premature decline of hCG or lack of its growth may be due to the threat of miscarriage or with a frozen pregnancy.

The picture shows a slightly different table expressing the level of hCG on days after IVF and the degree of its increase. Reduction of "DPP" means how many days have passed since the transfer of the embryo to the uterus. The table is convenient for use, you just need to choose the age or day of embryo replanting, and you will find the approximate proper level of hCG. Table data is compared directly with the result of the test for this hormone.

Interpretation of received data

Analyze the effectiveness of conception should be two weeks after the embryo is inserted into the uterine cavity. If the analysis for HCG with IVF is more than 100 mU / ml, then the pregnancy has come. This also means that the chances of bearing a child are very high. In addition, there is the term "biochemical pregnancy". That is, there is a significant increase in hCG above normal, but the pregnancy does not continue to develop. Therefore, it is important to know the dynamics of hormone growth, and not only its value in certain periods of pregnancy.

In case, when ECO hCG is low, that is, less than 25 mE / ml, this indicates that conception did not occur. Also, a low value of the indicator may indicate errors in the calculation of the gestation period, when the determination of hCG was too early. But when the hCG indicators for IVF are borderline between the two above - this is a rather dubious result. It is not excluded the development of ectopic pregnancy. In this case it is difficult to determine further tactics. Unfortunately, in most cases there is a gradual decrease in the level, and further attempt to keep the pregnancy does not make sense.

HCG and twins

But the level of hCG at double after IVF will be much higher. So at the first carrying out of the given analysis it is possible to receive result 300-400 мЕ / ml, that is more in two or three times. This is due to the fact that hCG is produced simultaneously by two organisms, and therefore the total amount of the hormone increases. Accordingly, the table of hCG at double after IVF will look like the above, only all the indices need to be multiplied by two.
