Do I need to test again??? Please help...

[rd7175]

I had unprotected oral sex and intercourse with a female whose status I don't know (but is questionable) on the following dates: 4/9/09, 5/10/09, 5/24/09 and 6/25/09.  I got tested for HIV on 7/27/09 using the following tests: HIV-1 DNA by PCR With HIV Antibodies by ICMA.  My result were negative.   Do i need to test again given the timeframes of my possible exposure to the virus?   I know I should allow at least 3 months for the antibody test, but i'm not sure how the PCR test may/may not compensate for the recommended 90 day timeframe.  Any reliable info you can provide would alleviate a lot of my anxeity.  Thanks!!

It doesn't, it's not an approved test for diagnosing HIV.

apparently (and i have this on expert medical advice) taking both tests at the window you described, at least one of those would have to come out positive if you were hiv positive.
to be 100% sure you need to follow up at 12 weeks.
