HIV Diagnostic TestingQuestion 4/10

Questions in Topic

A 26-year-old cisgender woman is seen at a family planning clinic and HIV testing is ordered. The clinic sends its HIV testing samples to a lab that performs an HIV-1/2 antigen-antibody immunoassay as the initial screening test and an HIV-1/HIV-2 differentiation immunoassay as the confirmatory test.

What is a major advantage of using the HIV-1/2 antigen-antibody immunoassay as the initial screening test as opposed to older algorithms that used an antibody test (HIV enzyme immunoassay [EIA])?
