HIV risk and testing: Nobody ever caught HIV from genital contact without penetration, and you really didn't need testing on account of this event. However these results taken together -- negative PCR at 10 & 22 days plus negative 3rd generation antibody test at 4 weeks is conclusive, or very close to it. For absolute 100% assurance, have another 3rd gen Ab test (or AgAb test, i.e. 4th generation) at 6 weeks.
