The presence of HCG in either blood or urine is a nearly perfect indicator of pregnancy, so doctors look for it in women with a positive result on a take-home pregnancy test.
The human hormone is called human chorionic gonadotropin or simply hCG. This hormone is produced by fetal trophoblast cells. It binds to the luteinizing hormone receptor on cells of the corpus luteum, which prevents luteal regression. Thus, hCG serves as the signal for maternal recognition of pregnancy.
