The FDA has approved the APTIMA HIV-1 RNA Qualitative Assay (Gen-Probe Incorporated, San Diego, CA). This assay enables people to learn with certainty whether they are infected within a few days rather than up to 6 months, as with an HIV antibody test. Unlike some approved antibody tests, the APTIMA assay is intended to detect only HIV-1 and not HIV-2.

The test could become a potential alternative to traditional Western blotting now used to confirm HIV-1 infection when screening results for HIV antibodies are positive. The APTIMA assay is approved for the diagnosis of primary HIV-1 infection for confirming HIV-1 infection when antibody results are positive.
