  • had the disease way back then and was already treated. now the result of my test was positive tpha and negative rpr. how was that?The two tests are used to assess different things. RPR is able to detect whether someone has active syphilis. But RPR can show a positive result for nearly 1 year (and rarely for 2 years) after successful treatment. TPHA is able to detect whether someone has ever had syphilis. This is used to 'double check' the RPR results (it is not biologically possible to have a positive RPR and negative TPHA).
