I was really really pissed because they didn't even have the damn sense to make sure that she didn't get it on the weekend. Needless to say, that weekend was hell. It turned out there was nothing there. Yet, I had to pay for 'another' more expensive visit to make sure. BASTARDS!
They prolly got that contingency covered in the legal release that almost nobody actually reads. It’s a pre-screen which errs towards false positives at best.
As for the original case, it seems like no good deed goes unpunished. They ought to tell anybody who comes up with a positive HIV test to check it a second time before making any personal plans based on the result.
