Human chorionic gonadotropin (hCG) is a specific protein-hormone that produces chorion cells during pregnancy after implantation of the embryo into the uterus. The results of hCG during pregnancy enable early pregnancy (on day 6-10 after fertilization) to determine pregnancy. HCG consists of two units - alpha and beta. To obtain the result of the analysis, beta (beta-hCG) in the blood of a pregnant woman is needed. How to understand the results of HCG tests, where to turn to donate blood to a pregnancy hormone and then get a competent HCG interpretation of the results.
HGCH blood test - transcript
The control of the result of this analysis is mandatory because the right level of the hormone hCG is very important for the normal development of pregnancy.
The result of hCG during pregnancy can be overestimated in multiple pregnancies (in proportion to the number of fetuses), diabetes mellitus, fetal pathologies (multiple fetal malformations, Down's syndrome), toxicosis, and with improperly determined gestation.
The result of a blood test for hCG can be lowered with a frozen pregnancy, delayed fetal development, a threat of miscarriage, placental insufficiency. The result of hCG in ectopic pregnancy can also be reduced.
Results of the HCG analysis decoding
| The gestation period is weekly, starting from the first day of the last menstruation | The level of hCG (mU / ml) |
|---|---|
| 3-4 weeks | 25-156 |
| 4-5 weeks | 101-4870 |
| 5-6 weeks | 1110-31500 |
| 6-7 weeks | 2560-82300 |
| 7-8 weeks | 23100-152000 |
| 8-9 weeks | 27300-233000 |
| 9-13 weeks | 20900-291000 |
| 13-18 weeks | 6140-103000 |
| 18-23 week | 4720-80100 |
| 23-31 week | 2700-78100 |
How to understand the results of hCG?
In this case, the norms for deciphering hCG during pregnancy are given for the periods of pregnancy not according to the terms of the last menstruation, but from the moment of conception. In each b-hCG laboratory, the decoding is done according to its norms, therefore the results obtained by you may differ slightly from those indicated. Therefore, donating blood to HCG decoding results must be done in the same laboratory.
The decoding of hCG during pregnancy throughout the term will show a gradual increase in rates. So, during the first trimester the result of the analysis of hCG will grow very rapidly, almost doubling, every 2-3 days.
At the 10-12th week, the analysis of the hCG during pregnancy will show the highest hCG level. Then the interpretation of the results of HCG will show a slow decrease in indicators to a certain level, which remains constant until the birth itself.

If in the body of a man or woman with the delivery of blood to oncomarkers deciphering hCG will give increased results, this is characteristic for embryonic types of cancer or ovarian cancer.
