When do they donate HCG? All answers here

The abbreviation of HCG means the name of human chorionic gonadotropin (it is a hormone that produces the placenta, but it can also produce tumors).

The pregnancy test works by the principle of determining the presence of this hormone in the woman's urine (but the presence of pregnancy can be confirmed only after the first week). HCG helps form the yellow body of the embryo and helps in the production of steroid hormones. Before you donate blood to the level of HCG, you must specify the date of the onset of the last month. The analysis diagnoses pregnancy on the first or second day of the delay.

For what purpose and when do they donate HCG?

1. To confirm the pregnancy.
2. If you suspect a ectopic pregnancy.
3. If you suspect a threat of miscarriage, a frozen pregnancy.
4. To identify tumors (because they can produce a large amount of this hormone).
5. To identify the causes of amenorrhea.
6. After treating an ectopic pregnancy, make sure it's successful.
7. If suspected of trophoblastic disease.
8. To diagnose the dynamics of fetal development.

In humans, the normal level of this hormone should not be more than 2.5 mU / ml, and in the last weeks of pregnancy it can reach 3000 mU / ml.

When to take HCG?

This analysis is part of the screening tests that women undergo at the 10th and 14th week of pregnancy.

If the results of the analysis showed that your level of chorionic gonadotropin is too low (in comparison with the period of pregnancy), then there may be several reasons for this:

- An incorrect pregnancy period is indicated (an error even in 7 days may distort the result of the study);

- Probably, there is a frozen pregnancy or ectopic;

- threat of abortion;

- the fetus develops with a delay;

- the placenta does not work properly;

- fetal death (if the low level is observed in the 2nd and 3rd semesters of pregnancy).

When do they donate blood for HCG for the first time? As stated above, you need to do this analysis for a period of about 10 weeks. But in any case, only analysis is not an indicator. Therefore, a woman must additionally undergo an examination with a doctor, ultrasound procedure and re-pass the procedure for donating blood from the vein.

The level of hCG increases in proportion to the developmental period of the fetus. If pregnancy is prolific, then the norms of indicators are also doubled. Still it is necessary to consider, that term of pregnancy can be specified incorrectly. But there are cases when the high content of this hormone should alert. After all, this fact can indicate the presence of diseases in the mother (toxicosis, diabetes), ectopic pregnancy, pathology of the fetus. In a word, an obligatory condition, when donating blood to HCG - any suspicions about the abnormal course of pregnancy. This analysis can provide important additional information.
