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 Washington
The RPR test works by looking for reagin, a group of antibodies associated with syphilis infection.
When a person is infected with syphilis, the immune system produces antibodies that can interact with cardiolipin, a lipid component used in the RPR reagent. A positive result therefore signals that such antibodies are present, but it does not confirm syphilis on its own, because other conditions can occasionally produce the same reaction.
RPR results are usually reported as a titer, a number that reflects how much the sample must be diluted before the reaction disappears. A higher titer generally suggests more active infection, while a lower titer may indicate an earlier, treated, or resolved infection. Clinicians often compare titers over time to judge whether an infection is responding to treatment.
Because the RPR test can produce false positives, a reactive result is typically followed by a confirmatory treponemal test, such as a TP-PA or an enzyme immunoassay. The RPR test is also used to monitor treatment response, since titers usually decline after successful therapy. It is not a substitute for direct detection methods in certain stages of syphilis.
