Order RPR Test (Syphilis) | Rapid Plasma ReaginThe rapid plasma reagin (RPR) test is a blood test used to screen for syphilis, a bacterial infection caused by Treponema pallidum. It detects antibodies that the body produces in response to the infection, rather than the bacterium itself. Because those antibodies can take time to appear, the RPR test is most informative when interpreted alongside a person's history and any follow-up testing.
About RPR Test (Syphilis) | Rapid Plasma Reagin in Colorado Springs
The RPR test is a nontreponemal assay, meaning it identifies antibodies that react with cardiolipin, a substance released when tissues are damaged during infection.
RPR testing works by mixing a blood sample with a reagent containing cardiolipin. If reactive antibodies are present, the sample clumps, or flocculates, which the laboratory reads as a positive result. The test is inexpensive and widely used as an initial screen because it can detect active infection across different stages of syphilis.
A reactive RPR result is not a diagnosis on its own. Other conditions, including certain autoimmune diseases, pregnancy, and some infections, can produce a false-positive result. For that reason, a reactive screen is typically confirmed with a treponemal test, such as a TP-PA or an enzyme immunoassay, that detects antibodies specific to Treponema pallidum.
The RPR test is also used to monitor treatment. Antibody levels, reported as a titer, tend to fall after successful therapy, so comparing titers over time can help clinicians judge whether an infection has resolved or is persisting. A rising titer may suggest reinfection or ongoing disease, while a stable low titer can sometimes reflect a treated past infection.
