Human chorionic refers to human chorionic gonadotropin, typically 1408 mIU/ml of human chorionic gonadotropin on day 36 of pregnancy may be normal, depending on the doubling. Human chorionic gonadotropin is a glycoprotein hormone. Normally, the range of human chorionic gonadotropin should be between 3,500 and 115,000 mIU/ml on the 36th day of pregnancy, however, human chorionic gonadotropin 1408mIU/ml may also be normal, and usually peaks at 8-10 weeks of gestation at about 50,000-100,000 U/L. If human chorionic gonadotropin doubles poorly every other day and remains at 1408 mIU/ml for a prolonged period, it is not normal. If the dynamic measurement of human chorionic gonadotropin level is normal, there is no need to worry too much, usually pay more attention to rest and close observation. Pregnant women need to go to the hospital on time and closely observe the changes of human chorionic gonadotropin.
