Hiv-duo Test

The HIV duo test gets its name from the antigen and antibodies it detects. This test detects the anti-HIV 1, anti-HIV-2 total immunoglobulins, and HIV-1 p24 antigen. The p24 antigen are detectable as early as 28 days of sexual exposure. Hence HIV infection can be detected early, resulting in a better prognosis. These are also known as fourth-generation HIV tests.
