About RPR Test (Syphilis) | Rapid Plasma Reagin in Sioux Falls
The RPR test is a nontreponemal assay, meaning it identifies antibodies associated with syphilis rather than components of the bacterium.
The RPR test works by mixing a blood sample with a reagent containing cardiolipin, lecithin, and cholesterol. If reagin antibodies are present, they bind to the reagent and cause visible clumping, known as flocculation.
Because reagin antibodies can also appear in conditions other than syphilis, a reactive RPR result is typically confirmed with a treponemal test, such as the T. pallidum particle agglutination assay or an enzyme immunoassay.
RPR testing is often used for screening and for monitoring treatment response. Antibody levels, reported as a titer, can decline after successful therapy, which helps clinicians track whether an infection has resolved.
