This test is to confirm HIV and find out if you have HIV-1 or HIV-2. Repeatedly reactive HIV-1, 2 antigen/antibody screening results are confirmed with an HIV-1/ HIV-2 antibody differentiation test. Negative or indeterminate results for HIV-1/2 antibody differentiation are confirmed with a quantitative PCR test. 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. 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 symptomatic or asymptomatic individuals. Combination HIV antibody and HIV antigen test—this is the recommended screening test for HIV. It is available only as a blood test.

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. An antigen/antibody test looks for both HIV antibodies and antigens.

If you have HIV, an antigen called p24 is produced even before antibodies develop. Antigen/antibody tests are recommended for testing done in labs and are now common in the United States. This lab test involves drawing blood from a vein.

(HIV-1 is the most common type found in the United States, while HIV-2 … Reactive HIV-1/-2 antigen and antibody screening test 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. Reactive result of this assay does not differentiate among reactivity with HIV-1 p24 antigen, HIV-1 antibody, and HIV-2 antibody. 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 … The term reflexes, in this case, means that the test is designed such that if a person has a positive HIV-1/2 antigen and antibody test, the lab will automatically perform a confirmation Western Blot test (reflexively). This streamlines the testing so that the person does not have to have a second blood draw for the confirmatory test. 2020-08-31 Interpretation. Negative results for HIV-2 antibodies usually indicate the absence of HIV-2 infection. However, in patients with reactive initial combined HIV-1/-2 antigen and antibody test results, such negative results do not rule-out acute or early HIV-2 infection.
