RPR (rapid plasma reagin) with reflex is a blood test that screens for syphilis, a sexually transmitted infection caused by the bacterium Treponema pallidum. Here are some reasons why you may need to have this test:
To screen for syphilis: RPR with reflex is one of the most commonly used screening tests for syphilis. Syphilis can cause a wide range of symptoms, including genital sores, rashes, fever, and fatigue. However, many people with syphilis have no symptoms, which is why screening tests like RPR with reflex are so important.
To confirm a syphilis diagnosis: If your RPR with reflex test is positive, additional testing will be done to confirm the diagnosis of syphilis. This may include a confirmatory test like the treponemal antibody test (TPPA), which detects antibodies to T. pallidum.
To monitor treatment: If you are diagnosed with syphilis, your healthcare provider will prescribe antibiotics to treat the infection. RPR with reflex can be used to monitor your response to treatment and ensure that the infection has been effectively treated.
To screen for other conditions: In some cases, RPR with reflex may be used to screen for other conditions, such as autoimmune diseases or certain cancers.
It’s important to discuss the results of your RPR with reflex test with your healthcare provider to determine if any additional testing or treatment is needed. If you are sexually active, it’s important to get screened for syphilis and other sexually transmitted infections regularly, even if you don’t have symptoms.
