The HIV 4th gen test kit is a lateral flow immunoassay for the simultaneous detection and differentiation of anti-HIV-1/ anti-HIV-2 antibodies (IgG, IgM,IgA) and P24 antigen in human serum, plasma, or whole blood. It is intended to be used as a screening test and as an aid in the diagnosis of infection with HIV. Any reactive specimen with the HIV 4th gen test kit must be confirmed with alternative testing method(s) such as ELISA or PCR.
