After a high risk exposure, I have taken 3 in home Oraquick Oral Swab HIV tests. These were taken at 3 months, 4.5 months and 6 months following the exposure. There is a lot of information floating around concerning these tests and how they can produce false negatives and may only be 92% accurate. Do I have any reason to doubt my 3 negative results well outside the window period. Would it be even remotely possible to have 3 separate false negative results?
