RPR (rapid plasma reagin) is a screening test for syphilis. It looks for antibodies that are present in the blood of people who have the disease. The test is similar to the venereal disease research laboratory (VDRL) test. Reference from A.D.A.M.
As a confirmatory test for a positive result from a serum screening test (RPR for example). Since the test has high negative predictive value it is very useful in both serum or CSF to exclude/rule out neurosyphilis if the FTA test result is negative.  A negative FTA in serum excludes neurosyphilis.
