Human Chorionic Gonadotropin 13.59

When the sisters were surprised to find that the pregnancy test stick showed two lines, they went to the hospital to confirm whether they were pregnant. At this time, the doctor undoubtedly asked them to measure HCG. Sisters who hear this professional term for the first time must be confused. Below we will sort out the relevant knowledge of HCG in detail.

What is HCG?

HCG in Chinese stands for human chorionic gonadotropin. It is a hormone secreted by the embryo. It can be detected in the mother's blood cells 10 days after fertilization. It is the most sensitive way to diagnose early pregnancy.

HICG plays a very important role in the growth and development of the fetus and pregnant mothers. HCG can promote the corpus luteum of the pregnant mother's ovary to secrete female hormones and estrogen again, and promote the uterine wall to be receptive to the implantation of the fertilized egg. HCG can stimulate the corpus luteum cells of the ovary, maintain the life of progesterone, and make it continue to develop into pregnancy progesterone.

Is the higher the HCG, the better?

Since HCG has so many benefits, does it mean that the higher the HCG level, the better? Actually not.

The HCG level in the pregnant mother's blood changes greatly at different stages of pregnancy. When you are not pregnant, your body's HCG level is <5IU/L, or it cannot be measured at all. On the 6th day after pregnancy, trophoblast cells begin to metabolize a small amount of HCG, and HCG can be detected in the blood on the 10th day. After the fertilized egg implants, HCG in the expectant mother's blood increases exponentially, reaches a peak in the 8th week, and then slowly maintains until the 12th week. After the 12th week, the HCG level in the pregnant mother's blood decreases rapidly; in the middle and late stages of pregnancy, the HCG concentration is only 10% of the highest value; it returns to the pre-pregnancy level within 2 weeks after giving birth, which means it cannot be measured.

The actual standard values ​​can be referred to as: 7-10 days of pregnancy >5 IU/L, 30 days of pregnancy >100 IU/L, 8-10 weeks of pregnancy 50,000-100,000 IU/L, 14 weeks of pregnancy 10,000-20,000 IU/L.

The individual differences in HCG concentration are very large. In other words, the square root of HCG levels in blood cells varies greatly among pregnant women. Therefore, after obtaining the HCG report, pregnant women should compare it vertically based on their own weeks of pregnancy to see the trend of HCG changes, rather than blindly comparing themselves with other pregnant women.
