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.

No: Testing at 90 days is conclusive, as long as there has not been interval exposure.
