Macro vue rpr card test kit

Study participants were assessed for syphilis infection with RPR testing (BD Macro-Vue RPR Card Test Kit, Beckton Dickinson, Franklin Lakes, New Jersey) and quantitative treponemal pallidum particle agglutination testing (TPPA Serodia, Fujirebio Diagnostics, Tokyo, Japan) using a cut-off value of >1:80. Study participants who were HIV uninfected were re-tested for HIV during each study visit with HIV Ag/Ab EIA fourth-generation sera tests (Genscreen ULTRA HIV Ag-Ab, Bio-Rad, Hercules, California). Western blot testing (NEW LAV BLOT I, Bio-Rad, France) was conducted for confirmation of all specimens that had a reactive HIV test according to the Peruvian national testing standards.^{16 (link)} During the PET scan visit, participants with HIV infection were asked to report their most recent CD4 T cell count and viral load. Rapid point-of-care tests were also used to diagnose participants with syphilis (Alere Determine Syphilis TP, Alere, Waltham, Massachusetts, USA) and HIV (Alere Determine HIV 1/2, Alere, Waltham, Massachusetts, USA) at each study visit. Our study did not find any discrepancies in the point of care when compared with standard serological tests for syphilis.
