What does a positive pregnancy test confirm?

A positive pregnancy test is designed to detect the presence of human chorionic gonadotropin (hCG) in the body, a hormone produced during pregnancy. Thus, a positive result confirms that a person is potentially pregnant, indicating that fertilization and implantation of an embryo may have occurred.

While the other options might be related to reproductive health, they do not accurately reflect the purpose of a pregnancy test. For instance, positive ovulation indicates ovulation has occurred but is not confirmed by a pregnancy test. Menstrual irregularities and potential infertility are broader conditions that may or may not be related to pregnancy and would require further evaluation and testing for diagnosis. Therefore, the primary and correct interpretation of a positive pregnancy test is the confirmation of a potential pregnancy.
