False-positive test result
A false-positive test result is one that appears to detect a disease or condition when in fact it is not present. A false-positive test result may thus suggest that a person has the disease or condition when they do not.
For example, a false-positive pregnancy test result would be one that appears to detect the substance (human chorionic gonadotropin) that would confirm pregnancy, when in reality the person is not pregnant.
