RPR

The Fortress Diagnostics Rapid Plasma Reagin or RPR Card test is a non-treponemal method for the serological detection of syphilis.  The antigen– a particulate carbon suspension coated with lipid complexes – agglutinates in the presence of serum reagins.  Reagins are antibodies present in the sera of syphilitic patients.  Visible agglutination in the form of black clumps which can be viewed macroscopically, indicate the presence of such antibodies in the sample tested.
