Answer

Hi The testing guidelines are to be tested 90 days after exposure and as long as there are no other exposures during this time the results are considered conclusive. Since your exposure was 5 years ago and your recent test was negative and from what you have described to me you are HIV free. Once HIV is present in the body the test will always come back positive. I have been positive for almost 22 years and we were just training individuals on testing and ran a test on me. My viral load is undetectable and I have no symptoms, but my test came back positive still. So you can see that if you had HIV the test will show it and the antibodies never go away.

Be well and stay safe, Shannon
