I have recently been unexpectedly diagnosed with Syphlilis though getting some blood tests required for a dental procedure.   My last full check was in May 2024, and were negative. I have no symptoms  normally associated with his disease (chancre or rash). the PRP was marked 1:512. The Pathologists have classed it as "consistent with early syphilis".

Welcome back to the Forum.  Sorry to hear of your recent diagnosis.  Your negative test in May 2024 and the strength of the RPR titer suggest that you acquired your infection in the past year or so.  As a result sexual partners in the interval since your infection have been exposed to your infection.  I trust that you have been treated.  The absence of symptoms does not mean that there were not signs of infection in the past that were not noticed or attributed to some other cause.---
