RPR Carbon Test

Professional-use RPR Carbon Test kit for in-vitro qualitative and semi-quantitative detection of non-treponemal reagin antibodies in serum or plasma. The RPR Carbon reagent combines RPR antigen with activated-carbon microparticles to make agglutination visible to the naked eye. Includes positive and negative controls.

The source describes RPR as a modified VDRL antigen and explains that visible agglutination indicates a positive reaction. 250 tests per pack, manufactured by Biomaxima S.A. Stated incubation: 8 minutes; sensitivity 86.0%; specificity 98.0%; storage 2–8 °C; shelf life 18 months.
