Hello, I would like to ask some questions. Five weeks after my behavior, syphilis tppa and trust are negative. What is the probability of eliminating syphilis?
Greetings.
It depends on your risk. If it was unprotected vaginal or anal test, you should retest at 6 weeks and, If you or your partner have syphilis symptoms, test again at 12 weeks.
In theory, 5 weeks is not enough to rule out syphilis.
Oral ulcers have various causes, and only a small fraction of those is syphilis-related. Extragenital syphilis ulcers (like on the tongue) are not too common, and syphilis is uncommon in developed countries (not sure where you had your risk) and 5 weeks TPPA is quite reliable. I wouldn't worry too much.
But, if there is no way for your partner to test, you should retest in 2-3 weeks.
