WebFeb 2, 2024 · Besides the superior performance, the ELISA technique has plenty of advantages over conventional flocculation screening tests (RPR). The method is designed potentially to be automated plus the reading of results is usually carried out by a microtiter plate reader, thus making the interpretation of results objective, unlike that of the RPR … WebSyphilitic infection leads to the production of nonspecific antibodies that react to cardiolipin. This reaction is the foundation of non-treponemal assays such as the VDRL (Venereal Disease Research Laboratory) test and rapid plasma reagin (RPR) test. Both these test are flocculation type tests that use an antigen-antibody interaction.
