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.
This hormone is released after the fertilized egg attaches itself to the wall of your uterus, while its amounts increase as the pregnancy progresses. How soon a pregnancy test will be able to detect this hormone depends on its sensitivity because some are able to detect HCG only when released in large enough amounts. As a result, a pregnancy test that is not able to detect small amounts of HCG will give you a negative result if you take it too soon.
