Rapid Plasma Reagin (RPR Test)
What does Rapid Plasma Reagin (RPR Test) measure?
The Rapid Plasma Reagin (RPR) test is a blood test that detects antibodies that may be produced in response to syphilis infection. It may be used as a screening test, to support evaluation of possible syphilis, or to help monitor response to treatment. An abnormal result usually requires confirmation with a more specific syphilis test and should be interpreted alongside symptoms, medical history, and other findings.
