RapidRod:
No that is not a conclusive test at 28 days.

Yes, which is why tests tend to skew towards the sensitive rather than the accurate.  Which is why multiple tests, taken at the appropriate time, constitute a valid HIV diagnosis.

A PCR test, if reactive, must be followed by a standard ELISA/WB test at 13 weeks, along with post-diagnostic testing, to fully confirm HIV.

That's an impossible question to answer without considering the circumstances. In your case (protected sex) it was a waste of money as you didn't have a risk of an infection - however if it calmed your fears than maybe for you it was worth the money.

Most people in your situation would be advised against taking the PCR test and to simply screen for HIV as part of their annual health/std check up. (ie no need to rush out and test because of an instance of protected sex)

yes, I understand but condoms aren't a 100% guarantee
