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 he or
she does 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 woman is not pregnant.
