Follow-up testing of individuals with reactive rapid HIV test results


This test is not offered as a screening or confirmatory test for blood donor specimens.

Reflex Tests Lists tests that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial tests.

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

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 confirmation/differentiation test by immunochromatographic method is performed at an additional charge.


If HIV-1/-2 antibody confirmation/differentiation is negative for both HIV-1 antibody and HIV-2 antibody, or indeterminate/negative for HIV-1/HIV-2 antibody, or indeterminate/indeterminate for HIV-1/ HIV-2 antibody, then HIV-1 RNA detection and quantification is performed at an additional charge.
