Detects: Recent and past HIV-2 infection.
By using polymerase chain reaction (PCR) technology, the HIV DNA PCR test can detect infection much earlier than other tests. The ideal time to take the screen is 28 days post-exposure; however, it can provide reliable insight within a few days of exposure. HIV-2 is primarily limited to western African nations, including the Ivory Coast and Ghana. It is rare to encounter the virus outside of these areas; however, if you feel you may have had an exposure to HIV-2 this test is the best way to get reliable results as early as possible.
