Quizplus · Accepted Answer

Initial testing for HIV status is done using enzyme-linked immunosorbent assay (ELISA). However, patients who do not have HIV but are positive for other disorders, including Lyme disease and syphilis, may give a False positive ELISA for HIV. Western blotting has increased specificity for HIV and is used as a confirmation of an ELISA that indicates HIV-positive.
