Another question about DNA PCR tes

Hi guys,

I have a question about DNA PCR test. I already went over the archives and I know that:

1. The only conclusive test is ELISA after 3 months (though after 6+ weeks its reliable in high percentage)
2. DNA PCR is not FDA approved
3. It has false positive and its more expensive

I am aware of all these things, no need to mention them if you reply... still i am anxious (maybe for no reason) and I would like to take the DNA PCR test. My question is: how reliable is it after 23-24 days? can you say it gives 95% confidence interval? is it better to wait until 28 days? I am just anxious and impatient... I had unprotected vaginal sex just for like 2 seconds before i came to my senses and got out but i understand i am considered under risk...

Thank you

Please try to avoid telling me i need to wait 3 months for antibody test, i know that! i am trying to get something before that time...
