What does a positive pregnancy test confirm?

A positive pregnancy test confirms the presence of the hormone human chorionic gonadotropin (hCG) in the urine or blood, which is produced shortly after a fertilized egg attaches to the lining of the uterus. This hormone indicates that a pregnancy is likely, but it does not confirm any specific details about the pregnancy itself.

For example, while a positive test indicates the possibility of pregnancy, it does not confirm the viability of the fetus, the presence of any complications, or the health of the fetus. Additionally, a positive result does not dictate any immediate actions, such as the need for prenatal vitamins or other prenatal care, which are important but not directly inferred from the test result itself. Therefore, the answer indicating a positive pregnancy test confirms possible pregnancy is the most accurate reflection of what the test signifies.
