BIO-RAD BioPlex 2200 REF 12000650 SYPH T PACK Syphilis Total & RPR Reagent Pack The BioPlex Syphilis Total & RPR kit is a multiplex flow immunoassay intended for the qualitative detection of total (IgG/IgM) antibodies to Treponema pallidum and the qualitative detection and/or titer determination of nontreponemal reagin antibodies in human serum or plasma

Due to two issues: 1) Customer complaints associated with greater than expected Rapid Plasma Reagin (RPR) reactivity which does not confirm with treponemal antibody test which may be due to a positive correlation between the mass COVID vaccinations and false reactive RPR results, and 2) During routine stability monitoring, an increase in mean bias above specification was observed which can cause elevated RPR reactivity potentially due to early shelf-life failure.
