20 июл. 2021 г. · The levels of hCG in a pregnant person’s blood rise rapidly, doubling every two to three days. This is known as hCG doubling time. hCG levels rise during the first 6 to 10 weeks of pregnancy then decline slowly during the second and third trimesters. As your pregnancy develops, the increase slows down significantly. In most normal pregnancies at an hCG level below 1,200 mIU/ml, the hCG usually doubles every 48-72 hours. At levels below 6,000 mIU/ml, the hCG levels normally increase by at least 60% every 2-3 days. A rise of at least 35% over 48 hours can still be considered normal.
