is hcg what tells the body its pregnant
Note: This hormone is not found in a non-pregnant womanâs body in high amounts. hCG is the same hormone used by pregnancy tests to determine if a woman is pregnant. Appropriate levels of hCG are less than 5 mIU/ml in non-pregnant women, and when levels are 25 mIU/ml or higher, a woman will be considered pregnant.
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.
