RPR (Monitor) with Reflex to Titer
This is a non-treponemal screening test for syphilis. False positive results may occur due to systemic lupus erythematosus, leprosy, brucellosis, atypical pneumonia, typhus, yaws, pinta, or pregnancy. Monitoring of RPR is helpful in assessing effectiveness of therapy.
A positive RPR screen must be followed by a specific treponemal antibody test (e.g., FTA-ABS):
A positive result on the second method confirms the screening result and the affected person is diagnosed with syphilis.
A negative result on the treponemal test may mean that the initial RPR test was falsely positive. Further testing and investigation may be done to determine the cause of the false positive.
False-positive results have been associated in patients with infections, pregnancy, autoimmune disease, old age, Gaucher disease, and malignancy.
