Abstract
A reaginic agglutination test for syphilis-associated antibodies is disclosed. The test uses an antigen reagent that comprises a buffered aqueous suspension of cardiolipin antigen ionically coupled to latex particles via a polypeptide bridge. Positive sera react with the antigen reagent and yield an agglutination pattern characterized by medium to large aggregates. Negative sera yield no agglutinated particles.
