This test begins with HIV-1/-2 antigen and antibody screen by chemiluminescence immunoassay. If the screen result is reactive, then HIV-1/-2 antibody differentiation test by immunochromatographic method is performed at an additional charge. If the HIV-1/-2 antibody differentiation test is negative for both HIV-1 antibody and HIV-2 antibody, or

HIV-1/-2 Ag and Ab Screen, P Antibodies against HIV-1 and HIV-2 are usually not detectable until 6 to 12 weeks following exposure and are almost always detectable by 12 months. They may fall to undetectable levels (ie, seroreversion) in the terminal stage of AIDS when the patient's immune system is severely depressed.

2012 May;54(1):42-7. doi: 10.1016/j 2020-06-06 Background: The capacity of HIV Antigen/Antibody (Ag/Ab) immunoassays (IA) to detect HIV-1 p24 antigen has resulted in improved detection of HIV-1 infections in comparison to Ab-only screening assays. Since its introduction in the US, studies have shown that the Determine HIV-1/2 Ag/Ab Combo assay (Determine Ag/Ab) detects HIV infection earlier than laboratory-based IgM/IgG-sensitive IAs, but HIV 1/2 Ag/Ab Combo The GS HIV Combo Ag/Ab EIA detects circulating antibodies to HIV-1(Groups M and O) and HIV-2, and it also detects HIV-1 p24 antigen. Thus, it is useful in evaluating patients with signs or symptoms of AIDS, and in establishing prior infection with HIV-1 or HIV-2.

The Determine HIV-1/2 Ag/Ab Combo assay (Determine Ag/Ab) is a single-use rapid test and is CLIA waived for fingerstick whole blood allowing its use in non-

Therefore a specimen can be identified as Ag positive, Ab positive, Ag and Ab positive, or Ag and Ab negative. Data taken from Masciotra S, et al. Performance of the Alere Determine™ HIV-1/2 Ag/Ab Combo Rapid Test with specimens from HIV-1 seroconverters from the US and HIV-2 infected individuals from Ivory Coast. J Clin Virol 2013: Published online 05 August 2013. DOI: 10.1016/j.jcv.2013.07.002 Reactive HIV-1/-2 antigen and antibody screening results suggest the presence of HIV-1 and/or HIV-2 infection, but it is not diagnostic for HIV infection and should be considered preliminary.
