Follow up question for example if i took z pak azithromycin today then how long i have to wait for test rpr to show conclusive result? thanks again?

Recommended post treatment testing of rpr is 6, 12 & 24 months after treatment to assure declining titers. And, of course, there should be no symptoms.

Get tested at 6 months after exposure/potential exposure to the infection.
