HIV Testing

How soon after a sexual encounter can one get an HIV test? I was tested three weeks afterwards and my results were negative. I heard that 90% of those who were infected would test positive at this point. I will get tested again but wanted to know how much confidence I can have in this result. I had protected oral sex three and a half weeks ago and am feeling muscle aches, diarrhea, headaches and slight fever. I am just concerned that these are symptoms of HIV and that my test was a false negative. Thanks so much for your help!

You posted your question in the wrong forum; see the IMPORTANT notice above.

Not quite 90% are positive by 3 weeks, but more than half of newly infected people have positive results by then.  For a more comprehensive reply, you'll need to re-post your question on the HIV Prevention and Safe Sex forum.

brooksand is wrong.  It is not necessary to wait 12 weeks for reliable testing.

hello mate i think you are getting yourself worked up the minimum time for you to have a test is12 weeks after you think you may have put your self at risk
i think probably you are making your self ill and you have picked up a virus
they very rarely give you a false reading if anything it could say you where positive and then they would re test
if it will help you go back to the clinic chat with a health adviser and if need be have another test
i having been having tests for years and years and i understand how you feel and your worries
stop beating yourself up and go and speak to someone
