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.
All pregnancy tests work by detecting the presence of human chorionic gonadotropoin (hCG), the pregnancy hormone. In both urine and blood pregnancy tests, the presence of the hormone human chorionic gonadotropoin (hCG) is evaluated. The hCG hormone is usually only present in blood or urine if a woman is pregnant. When an egg fertilized with sperm is implanted in the uterus of the woman the hCG is then produced.
