The AccuSet Syphilis Performance Panel 0820-0300 is intended for use by diagnostic manufacturers, researchers, and clinical laboratories to develop, evaluate, or troubleshoot syphilis test methods. Characterized samples and comprehensive data are provided for comparative analysis. Test results from commercially-available rapid plasma reagin (RPR) and Treponema pallidum antibody assays are included for characterization of the panel members. This panel of human plasma samples demonstrates a range of antibody reactivity for several RPR and Treponema pallidum test methods. One sample is included as a non-reactive sample and is negative for all RPR and Treponema pallidum test methods performed. For Research Use Only. Not for use in diagnostic procedures.
