This post IS anxiety related.  And pathological.  It causes me great sadness to see your return to our Forum.  I will not delete your post (yet) because I hope that the advice I am about to provide you will be helpful and that it will prove useful for other visitors to our Forum.  This is your 5^th post over the past month asking questions about long past, very low risk events.  That you are unable to move forward and continue to worry, and to spend money on tests strongly suggests that you have pathological, paranoid guilt over your prior behavior  In my opinion, you need help in moving forward and I suspect that until you get professional mental health help, you will continue to suffer.  I suggest (strongly) that you seek mental health evaluation over your fixation and that you print out the past 5 posts you have made on this Forum to illustrate the problem you are having.  Further posts, and further testing is a waste of time and money.

Because your questions may be helpful to others, I will provide brief comment.  I agree with the GP who told you “Real-time PCR is reliable for a positive result, not a negative result.”  OTOH however,  given the nature of your past exposure and the extensive testing you have (unnecessarily) had, you should have complete confidence that you did not acquire HIV and that you should move forward without further concern. 

I hope these comments are helpful to you, particularly my first paragraph.  There will be few, if any further responses.  EWH
