The basis of the test is that Most people become negative for RPR with adequate treatment, though some patients who present with later stage disease may maintain a low titer RPR (<1:8) for life despite adequate treatment. Question. For example, if the RPR was initially reported as 1:256, a value of 1:16 after treatment would indicate a lower level of antibody. Alternatively, for dilutions greater than 1:16, a 1:50 non-reactive serum-PBS solution is used. Can . Once an individual has been infected with syphilis, these tests will usually remain positive for life, and thus they are no longer useful in distinguishing new versus prior infection. Titer 1:1 - TheBody RPR Reactive with Negative Treponema pallidum????? - Women ... Secondary syphilis with a low titer RPR 2. RPR test is a screening test and it is notorious for producing false positives, so it should be backed up by a more specific treponemal test (like tppa, eia, there are a few). For patients who have been treated for syphilis, RPR titers should be followed (orderable as Syphilis Treatment Follow-up (RPR with Titer) in Epic). So 1:2 is a lower titer than 1:16 or 1:256 (which would be lots of antibody requiring lots of diluting to before you can no longer detect it). 2 These are defined as primary stage . 1:64 to ≤1:16) within 6-12 months from titer at time of treatment may indicate treatment failure.
