|Test Number||Components||Reference Interval|

The reflexed HIV-1/ HIV-2 Antibody Differentiation test discriminates between HIV-1 and HIV-2 antibodies. Results for each type are reported.
If the HIV-1,2 Combo Antigen/Antibody screen is repeatedly reactive, then the HIV-1/ HIV-2 Antibody Differentiation test will be performed. Additional charges apply. A recommendation to order further testing on a separate specimen for HIV-1 Nucleic Acid will be made for certain results. This multi-test algorithm was proposed by the Centers for Disease Control and Prevention (CDC) and adopted by the Clinical Laboratory Standards Institute (CLSI) for the diagnosis of HIV.
