What does hormone cause hCG?
Human chorionic gonadotropin (hCG) is a hormone produced by your placenta once an embryo implants in the uterus. The purpose of the hormone is to tell your body to continue to produce progesterone, which prevents menstruation from occurring.
What does hCG level mean?
HCG levels higher than 5 million international units per milliliter (mIU/mL) typically indicate pregnancy. Your first test result is considered a baseline level. This level can range from very small amounts of hCG (such as 20 mIU/mL or even lower) to larger amounts (such as 2,500 mIU/mL).
