Normal hcg value comparison table during pregnancy

After the embryo implants, human chorionic gonadotropin (HCG) is secreted by the germ cells of the villus trophoblast. The blood cell HCG concentration values ​​at different stages are as follows: 1. More than 5.0U/L on the 7th-10th day of pregnancy; 2. More than 100U/L on the 30th day of pregnancy; 3. More than 2000U/L on the 40th day of pregnancy; 4. More than 10000U/L in trophoblastic disease. The changing pattern of blood HCG can be used to diagnose intrauterine pregnancy or ectopic pregnancy. In a normal pregnancy, HCG continues to rise rapidly every day, and the increase in 48 hours exceeds 60%. However, in an ectopic pregnancy, HCG metabolism is less, and the increase in 48 hours is less than 50%.

There is no need to monitor the progesterone level until the late pregnancy. The most meaningful period for testing the progesterone level is from shortly after conception to 7 weeks of pregnancy, because during this period it is necessary to determine whether it is an ectopic pregnancy, whether the test tube embryo is developing normally, or whether the test tube embryo has stopped developing. After 7 weeks, it is important to check if the test tube embryo has a fetal heartbeat by ultrasound.

Normal growth and development, regardless of the level of progesterone, is within the normal physiological range. If the progesterone value is insufficient, the test tube embryo will be miscarried or stop growing. This possibility also exists before 12 weeks. After 12 weeks, the corpus luteum function of the ovary is replaced by the placenta function, and there is no problem of low progesterone during pregnancy. Therefore, after pregnancy, if the progesterone value is higher than 25ng/ml, the test tube embryo can generally grow and develop normally. If it is lower than 15ng/ml, the test tube embryo will not develop fully. If it is lower than 5ng/ml, the test tube embryo generally stops growing.

The duration of pregnancy and physical examination data also have certain references. Under normal circumstances, it is fine as long as it belongs to the normal range. The more days of pregnancy, the higher the HCG data may be. Generally, women's human chorionic gonadotropin is in the range of 1000-5000b250lU/mL between 4-5 weeks of pregnancy. As the fetus continues to grow and develop, the value of human chorionic gonadotropin will continue to rise. This value will reach its peak in the 8th week of pregnancy, which may reach around 20000b250lU/mL, and then continue to decline gradually. Therefore, pregnant women should go to the hospital regularly for routine physical examinations to understand their own health status and the development of their babies, so that they can make improvements in time.
