3 months post exposure is when you can obtain a conclusive test result.
sir, what I want to know is that if a man had intercourse with a woman who had intercourse with HIV infected man just 5 days ago, what would have happened.I have heard that 3 months is required for testing HIV.
It doesn't matter if you didn't ejaculate or had pre cum. You had an unprotected episode, albeit as brief as it was, you need testing. 12 weeks is conclusive.
