HIV 1/2 ANTIGEN/ANTIBODY,FOURTH GENERATION WITH REFLEXES

Additional Information:

Epic order code: LAB20147301

This test includes HIV antibodies by ICMA with HIV-1/HIV-2 supplemental antibody confirmation. If ICMA results are repeatedly positive, reflex to supplemental differentiation assay will be performed at an additional charge. Sera that are repeatedly reactive in two out of three tests will reflex to HIV-1/HIV-2 supplemental testing. Some individuals may be initially reactive by the preliminary test and negative or indeterminate by HIV-1/HIV-2 supplemental testing. This may be caused by other viral antibodies or autoantibodies that cross-react with the viral antigens, although this is extremely rare.
