First, this was zero risk for HIV, which is not transmitted by finger contact; you did not need testing for HIV. However, your negative RNA test at 15-16 days is additional proof you were not infected. If you still feel you need absolutely conclusive testing, have an HIV antigen-antibody (AgAb, "4th generation") blood test 6 weeks after the event.
