All antibody tests should detect the most common subtypes of HIV-1. The majority of HIV tests will also now detect HIV-2 and all but the very rarest of HIV-1 subtypes (usually only found in endemic areas in West Africa). A test that specifically detects the rare HIV-1 group O is also now available, though in most cases, a standard antibody test would identify a group O infection. For detailed information, see our page about HIV subtypes.
