Focus on this . . . NO RISK. Redundant testing questions are unnecessary. You didn't have a risk for HIV, end of story.
Somehow I think you are aware that we are going to tell you that you had nor risk. Which you didn't. So, not only was your test conclusive, it was also unnecessary because you will never get HIV this way. The only ways adults get HIV is from unprotected vaginal or anal sex or sharing of IV drug needles.
its conclusive and its a very sensitive test.
