Chances of 12 weeks negative 4th gen combo and pcr rna turning positive for hiv after an unprotected encounter with a female of unknown status? thanks
3 doctors weighed in across 3 answers
Very unlikely: HIV tests turn positive in over 90% of cases within six weeks. In order for you to have HIV several unlikely events would all have to come together: First, your partner had to have had HIV. Second, female to male transmission would have to have occurred. Third, you would have to be one of those very rare people whose tests only turn positive late.

Less than 1%: Multiple reports cite that the sensitivity (ability to accurately measure a truly negative test) of the 4th generation IV test is 100%. Examples given include 1 false negative/508 specimens, another 2 false negatives/669 tests. You are negative for HIV.

Very unlikely: Most sensitive HIV tests will be (+) within 30-35 days and the newer tests will be (+) in 10-20 days. I feel confident that your tests being negative at 90 days, and all the prior negative tests, means you can stop worrying.
