Advisory Information


This confirmatory assay should be ordered only on specimens that are repeatedly reactive by HIV-2 antibody screening immunoassay.

 

Screening, supplemental, or confirmatory serologic tests for HIV-2 antibodies cannot distinguish between active HIV-2 infection and passive transfer of maternal HIV-2 antibodies in infants during the postnatal period (up to 2 years). Diagnosis of HIV-2 infection in newborns and infants of less than 2 years old should be made by consistently positive nucleic acid test results, such as the presence of HIV-2 DNA/RNA (FHV2Q / HIV-2 DNA/RNA Qualitative Real-Time PCR).

 

New York State clients: This test should not be requested for maternal/newborn HIV screening on specimens originating in New York State, due to state regulatory requirements for expedited result reporting.
