RPR (Rapid Plasma Reagin) with Reflex to Quantitative RPR (Syphilis) LabCorp

The Rapid Plasma Reagin (RPR) test is to test for syphilis. This gold standard blood test looks for antibodies to the syphilis virus. If the RPR is positive, there is another test called a Treponemal pallidum test. This will be automatically run to confirm the result. Syphilis testing is important because a person can have syphilis without knowing it and can pass it along to a partner easily.
