What is the meaning of HIV-1 and 2 non reactive?

What does HIV-1 AB positive mean?

A positive result means that HIV antibodies were found and that you may have HIV.

What is a HIV-1/2 antibody test?

The HIV antibody test advised by the CDC is the HIV-1/2 antigen/antibody combination immunoassay test. If you test positive for HIV, the CDC advises the following follow-up tests: HIV-1/HIV-2 antibody differentiation immunoassay. This test is to confirm HIV and find out if you have HIV-1 or HIV-2.

What does reactive HIV 1 and HIV 2 mean?

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. A reactive result does not differentiate among reactivity with HIV-1 p24 antigen, HIV-1 antibody, and HIV-2 antibody.

Can a nonreactive HIV 1 antibody be used to diagnose AIDS?

87389 HIV-1 Ag/HIV-1 and HIV-2 Ab; if reflexed, add HIV-1 and HIV-2 Antibody Differentiation 86701 and 86702 Testing alone cannot be used to diagnose AIDS, which is a clinical syndrome. The diagnosis of AIDS must be established clinically. A nonreactive result does not exclude the possibility of exposure to or infection with HIV-1 and/or HIV-2.

What does a positive HIV 1 test mean?

Positive HIV-1 antibody but indeterminate HIV-2 antibody results indicates the presence of HIV-1 infection, with probable cross-reactivity of HIV-1 antibodies with HIV-2 antigens on the assay strip. Verification of a first-time positive test result is recommended for the diagnosis of HIV-1 infection.

When do antibodies to HIV 1 and 2 fall to undetectable?

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.
