It is recognized that currently available assays for the detection of antibodies to HIV-1 and/or HIV-2 may not detect all infected individuals. The performance of this assay has not been established with cadaver specimen, heat inactivated specimens or body fluids other than serum. If very early infection is suspected, order HIV nucleic acid testing (HIV PCR). If this result is inconsistent with the clinical picture, additional testing is suggested for confirmation. A nonreactive result does not exclude the possibility of exposure to or infection with HIV-1/HIV-2. HIV-1 p24 antigen and HIV-1/HIV-2 antibodies not detected. RESULT IS NOT DIAGNOSTIC (considered preliminary) and diagnosis of HIV infection must be based on supplemental test results specimen sent to reference lab for HIV-1/HIV-2 antibody differentiation assay.
The reactive screening HIV Ab/Ag Combo assay indicates possible presence of HIV-1 p24 antigen and/or HIV-1/HIV-2 antibodies.
