The only risks for HIV in adults are:
1) Having unprotected anal or vaginal sex, or
2) sharing intravenous needles with IV drug users.
You cannot get HIV from anyone's hands or fingers - not your hands/fingers, not anyone else's hands/fingers, even if the hand has blood or fluid on it. You didn't have a risk for HIV, so your questions about testing for HIV are not relevant.
Also, if you are not using intravenous drugs, your question is not relevant. This forum is for PERSONAL risk assessment and testing advice. It is not for questions that do not pertain to your situation or questions that make you curious.
Our members have fully advised you that you were not at risk for HIV. The window period only applies to people who were at risk for HIV, and who need to test for HIV. Since you had no risk, there is no window period to worry about. There is nothing more for our members to say about your no-risk event.
