For practical purposes, the combination of both negative antibody and PCR at 3 weeks probably is 100% secure. However, there has been no research to prove it, i.e. no studies of this particular test combination and timing. If I were in your situation, I would not have gotten tested at all; and if I had done so, I would now consider myself home free and would not be tested again. But if the lack of specific research makes you nervous, have confirmatory antibody test at 7-8 weeks.
Welcome to the forum.
First, you had a zero risk exposure. You had condom-protected sex, therefore from a risk standpoint, no HIV testing was necessary. Second, in the US, it is the rare commercial sex worker or stripper who has HIV. But most important, as long as HIV testing is done sufficiently long after the last exposure, the results are completely reliable -- and test results always overrule exposure history and symptoms, because the results are much more reliable. And you read some misinformation about the HIV DNA test. It is correct that the test is not perfect, but that's because it can given false positive results. However, a NEGATIVE result at 3 weeks is proof you were not infected. If you want still more proof, feel free to have an antibody test 7-8 weeks after the exposure, as you are planning to do. It will also be negative.
Really, this was a nothing event in terms of HIV risk. All is well.
I hope this helps. Best wishes-- HHH, MD
"Based on my encounter and my test results can I safely 100% say I am HIV Negative after this encounter?"
Yes. As in my original reply, it was 100% certain you were HIV negative before you were ever tested! In any case, the test results you have had care completely reliable.
HI Doctor,
This will be my final post. I just went to Planned Parenthood and took an HIV Rapid Test and the results of course came back negative.
I would have liked to have had 8 full weeks complete but due to a busy next two weeks I couldnt do so.
So I tested Negative at 21 days on a HIV DNA PCR and Antibody Test and Negative on a 54 day HIV Rapid Test.
Based on my encounter and my test results can I safely 100% say I am HIV Negative after this encounter.
Thanks in advance. Your comments and help in this post (and throughout the forum) has helped me tremendously and I really do appreciate it. I feel very relieved.
Thank you for the information Doctor. I really appreciate it and feel much better.
I did mean to add that the HIV PCR DNA test I took at 3 weeks also included an antibody test.
Based on your response and my testing I am assuming another test at 7-8 weeks is a waste of time and money as my tests at 3 weeks are conclusive?
This will be all for me and I do thank you very much.
