In a normally developing singleton pregnancy, quantitative serum HCG levels double every 2-3 days during the earliest weeks of pregnancy. This HCG calculator can be used to determine the doubling time of your HCG levels.
Human chorionic gonadotropin (hCG) is a hormone produced by the placenta of a pregnant woman. Early in pregnancy, the level of hCG increases in the blood and is eliminated in the urine. A pregnancy test detects hCG in the blood or urine and confirms or rules out pregnancy. During the early weeks of pregnancy, hCG is important in maintaining function of the corpus luteum. Production of hCG increases steadily during the first trimester (8-10 weeks) of a normal pregnancy, peaking around the 10 th week after the last menstrual cycle.
