how conclusive are 4th Gen tests at 12 and 20 weeks.

I have read a lot on this forum today.    I had a low risk encounter where I gave a blow job to a gay male.  I am also male.   I thought he was heterosexual and married to a woman and so when I found out he was gay, I immediately became concerned.  I have tested negative at 8 12 and 20 weeks with a 4th Gen test drawn from the veins.  I took an RNA test yesterday and am awaiting the results.  I am paranoid and scared as I am married and this was a one time thing. my symptoms are dry mouth and sore throat recently.  and body aches.

You don't need to test. RNA PCR wasn't necessary at all. As other members have stated, you were never at risk from your event.

Are you a male?  A big tip off that he is not hetrosexual is that you were sexual with him . . . just saying. For oral sex though, you had no risk for HIV.  The only risks for HIV are unprotected vaginal sex, unprotected anal sex or sharing IV drug needles.  That's it.  Saliva and air inactivate the virus.  No one in the history of HIV has been infected from oral sex that has been documented or proven.  You don't need a test at all for your encounter.

Oral sex would have never exposed you to HIV as there are at least 12 different substances in the saliva that neutralize the virus. The only ways HIV is spread are:
-Unprotected anal/vaginal penetrative sex.
-Sharing needles to inject drugs.
-Mother to child.

a 4th generation test is accurate 28 days after the exposure.

All the best.
