What about the following statement from Dr. H. Hunter Handsfield, M.D?
I'm so confused!

This has been explained before -- but this time I'm going to bookmark this thread so I can refer questions to it and won't have to keep repeating myself!
Many people misunderstand the duo (4th generation) HIV test. It might seem that after the period in which p24 antigen can no longer be detected in the blood (around 4-6 weeks), the test behaves just like a stand-alone antibody test. This would seem to leave open a possibility that after p24 antigen disappears, there could be brief time before antibody shows up, and therefore a possible false negative test result.
But it doesn’t work that way. The tests for HIV antibody and p24 antigen that are incorporated into the duo test are not independent of one another. It is the HIV antibody that clears p24 out of the blood. If p24 antigen is no longer detectable, then antibody MUST be present -- that's the very reason that p24 is gone. Therefore, in every person with an HIV infection of 4 or more weeks induration, either antibody or p24 is always detectable in the blood. (Both may be present for a couple of weeks in the 2-6 week time frame.)
So your negative result is definitive. Don’t have any more HIV tests. Do your best to move on. This thread is over.
So you are more concerned with kissing then uprotected sex? Or was the unprotected sex just a story?
HIV is transmitted by;
Unprotected penetrative anal and/or vaginal sex
Sharing works with other IV drug users
Mother to child
How sure are that deep kiss share no risk for HIV?
PCR test is useless for diagnosis.
What about the PCR test that test for the virus itself (viral load)? Would it make a difference on my situation?
The antigen part is basically useless after 1 month. Then the antibody part is conclusive at 3 months. But any negative test is a good test.
I had unprotected sex with the lady of unknown HIV status.
