Testing Algorithm Delineates situation(s) 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 the chemiluminescence immunoassay method. If HIV-1/-2 screen result is reactive, then HIV-1/-2 antibody differentiation test (by membrane immunoconcentration method) is performed at an additional charge. Depending on the HIV-1 and HIV-2 antibody results of this differentiation test, subsequent reflex tests such as HIV-1 antibody confirmation by Western blot and HIV-2 antibody confirmation by line immunoassay will be performed when appropriate and at an additional charge.
