You really needn't worry; for certain you do not have HIV. I understand how worrisome your symptoms may be, but several factors indicate HIV really should no longer be a concern for you. The exposure was very low risk, since the vaginal sex was condom protected and there has never been a known case of HIV transmitted by oral sex (oral to penis). Your sore throat was not HIV, which cannot cause symptoms of any kind sooner than 8-10 days after catching it; almost certainly you just caught a cold, which might have gone on to strep throat, which may explain why the injection (probably penicillin) was helpful. But most important, your test results are conclusive:  they prove for sure you do not have HIV. The AgAb tests are conclusive any time more than 6 weeks after exposure, and the RNA test conclusive after about two weeks. You have been really over tested -- don't have an. more tests, at 6 months or any other time.

And by the way, your circumcision status makes no difference:  although it slightly raises the risk of HIV if exposed, the test results overrule everything else. No matter how high the risk of HIV at the time, and no matter what symptoms there are, the test results tell the truth! Please don't worry any longer.

I hope these comments are helpful. Let me know if anything isn't clear.

1. If the symptoms are due to hiv, the ag/ab test will be positive few days later, and NAT test should be larger than 20 copies/ml immediately, is it right?

2. When I pulled the penis out of her vagina, the condom slid about halfway, but I felt that the condom still covered the foreskin. Can it be considered that condoms work?

3. My ag/ab test are smaller than 0.1 in korea clinic, but when I came back China, the result are 0.2. And doctors in China said that if larger than 0.5, it will be dangerous. Does is correct?

Thanks for picking my questions!

2. It is common for the penis to withdraw from a condom that remains in the vagina. Protection against HIV and other STDs is considered complete when it happens.

3. With almost all laboratory based HIV blood tests, any value below the negative-positive cut-off value is equally negative. The same specimen tested 10 times would give 10 different numbers. As long as the number is below the cut-off, the result is equally negative. (I am unaware of any tests whose cut-off is as low as 0.5; for all tests in the US and Western Europe it's 0.9 to 1.1 But perhaps there is a test in your country with cut-off of 0.5.)

In addition, I decide to take some anti-anxiety medicine if I still can't move on. Does the anti-anxiety medicine such as Mirtazapine affect the accuracy of hiv test?

They are my final questions. Thanks for you help!

There are no medications or medical conditions of any kind that have any effect on HIV test reliability. That was once the case with the earliest antibody tests, not used for many years.

It is 100% certain you do not have HIV. Do not overthink it and do not search the web any further, and for sure do not have any more HIV tests!

That completes the two follow-up exchanges included with each question and so ends this thread. I hope the discussion has been useful. Best wishes and stay safe.
