Brief Answer:
Please do a serum PCR test for m-RNA HIV virus

Detailed Answer:
Hi there.
I read your concerns & hear you; apologies I got to see this 24 hrs later.

From your description of events, Yes it appears that you have nothing to fear.
However from purely an 'academic' stand-point, ELISA negativity repeated at a 6 month interval should put you in the clear!

But if you don't wish to wait that long, please do a PCR test for m-RNA that will help detect even small quantities of the virus, get a negative result (as I envisage in your case) & then close this topic & carry on with your life!

Good Luck & Godspeed!
