Does hcg value of 20 mean pregnancy?

Under normal circumstances, if you want to confirm whether a woman is pregnant, you usually need to do a blood test. The blood test is to test the hcg value in the blood. If a woman is pregnant, the hcg value in the blood is generally high. However, the hcg value is not only used to detect whether there is pregnancy, but also to detect whether the embryo is developing normally. If the hcg value doubles, it is better, indicating that the baby is very healthy. Does the hcg value of 20 mean pregnancy?

Does hcg value of 20 mean pregnancy?

Generally, if the HCG level is greater than 5, pregnancy is considered.

What is the hcg value when pregnant for 20 days

Human chorionic gonadotropin enters the maternal blood after fertilization and proliferates rapidly until the 8th week of pregnancy, then slowly decreases in concentration until the 18th to 20th week, and then remains stable. Generally, an increase in the level of human chorionic gonadotropin to at least 2.5MoM is associated with Down syndrome. However, the actual average level of complete human chorionic gonadotropin in the maternal blood of DS patients is only 1.3MoM, which cannot clearly identify DS patients. The human chorionic gonadotropin-related molecules used for DS examination are free b-hCG and high sugar hCG (H-hCG).

The levels of human chorionic gonadotropin-related molecules are also related to the sex of the fetus. The levels of human chorionic gonadotropin in baby girls are significantly higher than those in baby boys.

Complete human chorionic gonadotropin is produced entirely by the syncytiotrophoblast of the placental chorion. Human chorionic gonadotropin is produced by trophoblast transitional cells and syncytial cells. Human chorionic gonadotropin begins to be secreted 10-14 days after conception. It has LH-like functions. Before the fetal pituitary gland secretes LH, it stimulates the fetal testicles to secrete testosterone to promote male sexual differentiation. It can also promote gonadal development. 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 combined pituitary deficiency. It can not only promote gonadal development and the secretion of male hormones, but also promote the development of secondary sexual characteristics.

How much hcg in the blood is pregnancy

The testing principle of blood HCG and urine HCG is the same, which is to check whether there is HCG embryo in the blood. If the early pregnancy test paper tests weakly positive, it is possible that you are pregnant. Only when there are two obvious red lines can you be considered to be really pregnant. If you are pregnant, there will be an embryo and a placenta will begin to form, which will produce HCG. At this time, HCG will appear in the blood circulation of the pregnant woman, and then in the blood and urine.

The HCG test determines whether a woman is pregnant by measuring the HCG value in her blood. It is more accurate and has a smaller error than early pregnancy test strips. It mainly checks the HCG value to determine whether the pregnancy is normal. It can confirm whether it is an early pregnancy 8-10 days after intercourse. The test results are usually available on the same day. If the test is done in the morning, the results will usually be known in the afternoon.

During early pregnancy, the HCG value is generally high and grows very quickly in the early stages, so the accuracy of checking pregnancy through this method is very high. In the later stages of pregnancy, the HCG value will gradually decrease and become more stable afterwards.
