Early Pregnancy Test Pregnancy tests are usually simple urine tests that show if a woman is pregnant. They test for a hormone called human chorionic gonadotropin (HCG). HCG is released when a fertilized egg attaches to the lining of the uterus. HCG is only found in a woman's body if she is pregnant.

What is the earliest day after a missed period that a person can take a home pregnancy test and expect it to be accurate?

- A special hormone, called hCG, is found in the urine of a woman that is pregnant, and is produced by the placenta. All of the tests, aside from blood tests, will use a woman’s urine to find a sufficient amount of the pregnancy hormone hCG. This hormone takes a few weeks to build up to a sufficient level for detection.

How Do Early Pregnancy Tests Work? The tests work by binding the hCG hormone, from either blood or urine, to an antibody and an indicator.
