What is the hcg value when you are pregnant?

How much is the hcg value in early pregnancy? Generally, the β-HCG radioimmunoassay value of ordinary people is lower than 3.1. If it exceeds 5, you may be pregnant. The hCG normal value during the entire pregnancy will vary with the advancement of pregnancy time. It will rise rapidly in the first 8 weeks of pregnancy, slowly decrease after about 8 weeks of pregnancy, and finally remain stable.

How much is hcg value in early pregnancy

The standard value of blood hCG is <10μg/L, and the standard value of β-hCG is <3.1μg/L. β-hCG is a part of hCG. Generally, the β-HCG radioimmunoassay value of ordinary people is lower than 3.1. If it exceeds 5, the possibility of pregnancy can be considered. If it exceeds 10, pregnancy can be basically confirmed. HCG can rise to over 2500IU/L 35-50 days after pregnancy. The urine -HCG level in women with multiple pregnancies often exceeds that in women with a single pregnancy. 9 days after giving birth or 25 days after an abortion, blood cell HCG should recover. If this condition is not met, the possibility of abnormality should be considered. The absolute values ​​of hCG in blood cells vary at different stages of pregnancy and among pregnant women. There is no comparability between them and they can only be compared with each other. During the first three months of pregnancy, hCG levels approximately double every 2.2±0.5 days.

Normal pregnancy blood hCG level chart:

0.2-1 week of pregnancy, 5-50, at this time the hCG value in the blood basically does not change, and the risk is not considered for the time being.

1-2 weeks pregnant, 50-500, every 2 days, if the β-hCG test result is not less than 66%, the possibility of ectopic pregnancy should be considered.

2-3 weeks of pregnancy, 100-5000, blood test results every 2 days, if the β-hCG level is not less than 66%, the possibility of ectopic pregnancy should be considered.

At 3-4 weeks of pregnancy, if the β-hCG level is 500-10000 and the blood test results are taken every 2 days and the level is not less than 66%, the possibility of ectopic pregnancy should be considered.

At 4-5 weeks of pregnancy, hCG is 1000-50000. 35-50 days after pregnancy, hCG can rise to more than 2500IU/L. If it is lower than this value, there may be a risk of threatened abortion.

5-6 weeks of pregnancy, 10000-100000. A sudden and sharp drop should alert you to the possibility of fetal intrauterine language retardation or pregnancy symptoms.

6-8 weeks of pregnancy, 15000-200000. A sudden and sharp drop should alert you to the possibility of fetal intrauterine language retardation or pregnancy symptoms.

In the second and third months of pregnancy, 10,000-100,000 is the highest value and it decreases partially, but it is still higher than before pregnancy.

What does hCG do?

The HCG blood test determines whether a woman is pregnant by accurately measuring the HCG level in her blood. Compared with traditional urine HCG, blood HCG is more accurate, has smaller deviations, and can be tested earlier. In order to detect the accuracy of pregnancy, doctors generally recommend blood tests for HCG pregnancy tests.

1. It has the functions of FSH and LH, maintains the service life of menstrual progesterone, and expands menstrual progesterone into pregnancy progesterone;

2. Promote the aromatization of androgen into estrogen and stimulate the production of progesterone;

3. Inhibit the stimulating effect of plant lectins on reticulocytes. Human chorionic gonadotropin can be adsorbed on the surface of trophoblast cells to prevent the test tube embryo trophoblast cells from being attacked by the pregnant mother's reticulocytes;

4. LH-like effect: before the fetal pituitary gland secretes LH, it stimulates the fetal testicles to secrete testosterone to promote male sexual division; it can also promote the development of sex hormones, and for men it can stimulate the activity of interstitial cells in the testicles and increase the secretion of androgen (testosterone). It is of great significance for the treatment of male patients with pituitary synergism. It can not only promote the growth of sex hormones and the secretion of androgens, but also promote the growth of secondary sexual characteristics.

5. It can fuse with TSH protein kinase in somatic cells of pregnant mother's thyroid cysts and stimulate thyroid cyst specificity.
