In a VDRL procedure, the patient’s serum is heat-inactivated and mixed with a buffered saline suspension of VDRL antigen containing cardiolipin, lecithin, and cholesterol that binds with reagin (an antibody-like protein).

WebRPR nPrinciple: Rapid Plasma Reagin (RPR) test nPatient sera mixed with a fine particle cardiolipin antigen which has been enhanced with cholesterol,lecithin, and charcoal will result in a macroscopically visible flocculation -type precipitation if the patient’s sera contains reagin - an antibody formed against cardiolipin. WebThe microparticulate carbon RPR antigen enhances the visual discrimination between reactive and nonreactive results. The reagin-type antibody binds with the antigen that is composed of a complex of cardiolipin, lecithin and cholesterol particles with activated charcoal.
