Possible exposure (protected but drunk) during last week December to first week January 2010 (by 10th?). Oral swab test on 1/29/10 in NYC clinic was negative. Subsequent NYC Elisa testing with my doctor on 2/2 (Neg on all STD's, HIV, Hep), 2/16 (Neg on HIV), 3/2 (Neg on all STD's, HIV, Hep), 3/12 (Neg on all STD's, HIV, Hep). So based on the duration between encounter and last set of negative tests, as well as the response I received from Dr.
