HCG is a glycoprotein secreted by human chorionic gonadotrophoblasts and consists of glycoproteins of α and β dimers, normal pregnancy at 2 to 3 weeks HCG is 100 to 5000 IU/L. Specifically each person’s physical condition is different and there will be some differences. Early HCG doubles very quickly, it is recommended to test the blood HCG every other day to determine whether it has doubled or not, if it has doubled, it means that the development of the embryo is relatively good.
