RPR (Rapid Plasma Reagin)

The RPR (Rapid Plasma Reagin) is a macroscopic screening test for the qualitative and semi-quantitative detection of Non-Treponema (reagin) in serum or plasma.

The kit contains RPR antigen which is  based on the easy to use VDRL carbon antigens. In the presence of the reagin, the antigen causes flocculation of the carbon particles, which appears as black clumps. The charcoal particles contained in the antigen suspension enhances the visual appearance  of the coagglutination in positive samples.
