Confirmation and differentiation of HIV-1 and HIV-2 antibodies in plasma specimens that show reactive results with third-(HIV-1/-2 antibody only) and fourth-generation (HIV antigen and antibody) HIV serologic assays This test is not useful as a screening test for HIV infection in …
Studies have shown that the HIV-1/HIV-2 antibody differentiation test more accurately differentiates HIV-1 and HIV-2 infections. 7 HIV-2 infection, while rare in the United States, is most commonly seen in persons from West Africa. It's important to differentiate HIV-1 from HIV-2, as HIV-2 may not respond to some HIV medications. 9; Question 7.
If HIV Antigen and Antibody, 5th Generation Screen is Repeatedly Reactive, HIV-1/2 Antibody Differentiation will be performed at HIV 1 & 2 Antibody (4th Gen) Test FDA-Approved HIV Antibody Test Our standard HIV test is the HIV 4th Generation Duo Antigen/Antibody Test. HIV-1/2 Antigen and Antibodies, Fourth Generation, with Reflexes. This test is used to screen and confirm HIV-1/HIV-2 infection (including acute infection) and to differentiate HIV-1 from HIV-2 infection. See also 1 related tests 2 related guides. HIV-1/2 Antigen and Antibodies, Fourth Generation, with Reflexes. HIV 1/2 Antigen/Antibody Blood Test . The HIV Antigen/Antibodies Test also known as the HIV 4th Generation Test, is the most common option for routine HIV Screening.

6 The HIV-1/HIV-2 antibody differentiation test can be performed more rapidly than can the Western blot method, so the turnaround time for confirmation of HIV infection is shorter. Indeterminate HIV-1 antibody but positive HIV-2 antibody results indicate the presence of HIV-2 infection, with probable cross-reactivity of HIV-2 antibodies with HIV-1 antigens on the assay strip. Verification of a first-time positive test result is recommended for the diagnosis of HIV-2 infection, by submitting a whole blood specimen for FHV2Q / HIV-2 DNA/RNA Qualitative Real-Time PCR. Indications: Alere Determine HIV–1/2 Ag/Ab Combo is an in vitro, visually read, rapid qualitative immunoassay for the simultaneous detection of HIV-1 p24 antigen and antibodies to both HIV-1 and Results of the screen cannot be used to distinguish between the presence of HIV-1 p24 antigen, HIV-1 antibody, or HIV-2 antibody. The reflexed HIV-1/ HIV-2 Antibody Differentiation test discriminates between HIV-1 and HIV-2 antibodies.
Positive HIV-1 antibody but indeterminate HIV-2 antibody results indicate the presence of HIV-1 infection, with probable cross-reactivity of HIV-1 antibodies with HIV-2 antigens on the assay strip.

The HIV Antigen/Antibodies test, also known as a 4th Generation HIV Test, looks for both antibodies to the HIV virus and the p24 Antigen which is specific to HIV. HIV 1/2 Antigen/Antibody Blood Test . The HIV Antigen/Antibodies Test also known as the HIV 4th Generation Test, is the most common option for routine HIV Screening. This test typically sees results in just 1-2 business days and is one of the most affordable HIV tests available. Test Code HIV12 HIV 1/2 Antigen/ Antibody - 4th Gen. Additional Codes.
If acute HIV-1 infection is suspected, detection of HIV-1 RNA (HIVQN / HIV-1 RNA Detection and Quantification, Plasma) or HIV-1 DNA and RNA (HIVP / HIV-1 DNA and RNA Qualitative Detection by PCR, Plasma) is recommended. HIV-1 Antigen and HIV-1 / HIV-2 Antibody (Human Immunodeficiency Virus) with Reflex to HIV-1/HIV-2 Antibody Differentiation Brief Description Specimens will be screened by using a CMIA test for the qualitative detection of HIV-1 p24 antigen, and IgM and IgG antibodies to HIV-1 and/or HIV-2.
