A pregnancy test is a diagnostic test that is done to determine if a woman is pregnant or not. It is a simple and convenient way to find out if conception has occurred. The test is usually done using a sample of urine, which is analyzed for the presence of a hormone called human chorionic gonadotropin (hCG).
A positive urine pregnancy test result indicates that hCG, which is only produced during pregnancy, is present in the woman’s body. When a woman becomes pregnant, the fertilized egg implants itself in the uterus, which triggers the release of hCG. This hormone is produced by the developing placenta and enters the bloodstream.
When a urine pregnancy test shows a positive result, it means that the levels of hCG in the urine are above a certain threshold, indicating that a pregnancy has occurred. The presence of hCG in the urine is a reliable sign of pregnancy and confirms the woman’s suspicions.
