Human chorionic gonadotropin (hCG, or human chorionic gonadotrophin) is a placental hormone initially secreted by cells (syncitiotrophoblasts) from the implanting conceptus during week 2, supporting the ovarian corpus luteum, which in turn supports the endometrial lining and therefore maintains pregnancy.
How does a test tell if you are pregnant or not? A pregnancy test detects the presence of a hormone called human chorionic gonadotropin (hCG) in your blood or in your urine. hCG is produced in the placenta shortly after the embryo attaches to the uterine lining and builds up rapidly in your body in the first few days of pregnancy.
