A member asked:

I've read that treponemal tests can only detect syphilis after a chancre has appeared, anything before that could be a false negative. i've tested at 8 weeks and 90 days (non-reactive), no chancres that i've noticed. are these conslusive?

Two negative treponemal tests at 2 and 3 months rule out syphilis.
