It’s possible to have a positive pregnancy test even if you aren’t technically pregnant. This is called a false positive. It’s sometimes caused by a chemical pregnancy. A chemical pregnancy occurs if a fertilized egg, known as the embryo, is unable to implant, or grow, very early on. self.comИзображение:self.comA false positive pregnancy test refers to a test result that shows a person is pregnant when in reality they’re not. Pregnancy tests check the urine or blood for human chorionic gonadotropin (hCG), a hormone produced during pregnancy. If hCG is detected, it typically means that the person is pregnant—but that’s not always the case. Getting a true false positive – one where you were never pregnant in the first place – is incredibly rare. Pregnancy tests detect the hCG (human Chorionic Gonadotrophin) hormone in your body, which is only present when you’re pregnant. This is why a positive pregnancy test result will mean you are almost certainly pregnant.
