The only risks for HIV in adults are:
1) Having unprotected anal or vaginal sex, or
2) sharing intravenous needles with IV drug users.
It is IRRATIONAL to think that any company would make an HIV test that could give people HIV. Antigens and antibodies do not infect people - only the live virus, which is NOT IN ANY TEST, can infect people with HIV.
There is no question you could ask, or any detail you could provide, that would turn your event into a risk for HIV. If you do not engage in any of the activities I listed above, you will NEVER get HIV.
