i cant seem to find a post where you've stated your exposure or if/when you've tested.
You've been here long enough to know PCR tests are not approved diagnostic tests. You only need an antibody test. If the test is positive then a comfirmative test will be given. (Western Blot or IFA)
What I'm really asking is at what point / symptoms (ignoring the PCR tests, and just say someone had only taken AB tests) would one have to consider alternative testing?
There is nothing to discuss. He doesn't have HIV even if he did have a risk.
But this guy had a no-risk encounter, plus PCRs. So it was obvious without the tests (if that was his only exposure).
Then I suggest you read Dr. Bob's response.
"Regarding your symptoms, I cannot diagnose the cause over the Internet. However, I can tell you what's not causing them. It's not HIV! Your negative HIV tests trump all symptoms! "
