The Syphilis Ab Rapid Test is a lateral flow chromatographic immunoassay for the qualitative detection of antibodies including IgG, IgM, and IgA to Treponema pallidum (Tp) in human serum or plasma. It is intended to be used as a screening test and as an aid in the diagnosis of infection with Tp. Any reactive specimen with the Syphilis Ab Rapid Test must be confirmed with alternative testing method(s) and clinical findings.
