A working girl performed oral sex on me in July and we had sex with a condom. I had an Insti test
6 weeks after which showed negative. I then had tonsilitus in August and was concerned when I
read that this could be a sign of HIV, so I repeated the Insti test at the begininning of November which
again showed negative. I've been reading on your site that Hep C could cause an Insti test to show negative, could this have been the case? Should I get re-tested for Hep and Insti again?
