I am not a doctor. But, something similar has happened that freaked me out. That day, my GP had three guys with the same panic story on his schedule. Not going to bother telling you about your risk. I wanted verification after it happened to me. So...
You can't afford to ignore the risk of possibly being exposed to Hep and Herpes. There is a vaccine for Hep A and B you should consider.
There's a 4-th generation ELISA test that tests for P24 antigen and HIV 1/2 antibodies in the blood. http://hivinsite.ucsf.edu/InSite?page=kb-02-02-01#S3X
Public health departments may prefer this test to the more expensive but more accurate PCR test that detects the HIV virus copies directly instead of the antibodies. http://molecular.roche.com/assays/Pages/COBASAMPLICORHIV-1MONITORTestv15.aspx
This latest development in PCR RNA testing is trusted to detect as few as 75 copies at 21 days.http://molecular.roche.com/News/LocalNews/Pages/FDAApprovesNewRocheDual-PCRTargetHIV-1Test.aspx
But, it isn't a quick-read type of test.
(really hope I didn't screw this up.)
