Scientists hope that the chip will eventually be able to diagnose HIV--which would require a blood sample. So you might also have people slashing themselves open, spilling blood all over the place, trying to self-diagnose under unsanitary conditions. Yeah, the will have a field day.

While I'm all about advances in medical science--and, being a lazy guy, a cheerleader for convenience--and I wholeheartedly support trying to stop the spread of STDs, this kind of project sounds about as responsible as telling a hypochondriac to self-diagnose on WebMD and then giving them free reign of a pharmacy.
