A member asked:
Would a 2-1-1 (on demand) prep, in which 2 tabs of truvada before sex exposure and 1 tab for next 2 days after exposure, increase the window period for 4th gen hiv test? if yes then when would be the best period for conclusive testing? thanks?

Unlike PEP, no data have been published on PrEP and delay of positive test results if it doesn't work. Logically, it shouldn't delay conclusive testing by more than a few days, maybe a week.
