Q: do i need to retest if my hiv ab/p24 ag screen was negative on day 40 after unprotected sex?

: Forty days is close enough to the official advice (6 weeks or 45 days) to be considered conclusive. However, if you had an especially high risk exposure, like unprotected vaginal or anal sex with a known infected person, it would be wise to have another test in a few more days.
