Is RPR positive for life?

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.

Which syphilis test is positive first?

A positive titer with a VDRL or RPR indicates active syphilis and follow-up serologic testing is performed to monitor treatment response. With this new testing algorithm that uses the treponemal test first, some patients may test positive for a treponemal test but test negative with a nontreponemal test.

Does syphilis stay in your body forever?
