Secondary – will occur in roughly 25% of patients with untreated primary syphilis, and manifestations may include a diffuse maculopapular rash involving the palms and soles, fever, and lymphadenopathy. Non-treponemal tests, like RPR and VDRL, detect antibodies to cellular components released during tissue damage caused by syphilis. Any specimen found to be reactive with a non-treponemal screening test should also have specific treponemal tests performed to confirm the diagnosis. The most likely scenario is that of non-specific reactivity, however the possibility that this is a very recently acquired infection needs to be given consideration and a detailed review of any of the risk factors should be made. Laboratory diagnosis and interpretation of tests for syphilis. With or without treatment, non-treponemal test titres will decline over time.

If tested, serology may be non-reactive, and it must be repeated if there is suspicion of primary syphilis. If prior serology is not available to confirm that infection dates back less than one year, patients should be considered to have late latent syphilis.
