I had unprotected sex with a girl I didn't know about 8 weeks ago. 3 weeks after possible exposure I took an Oraquick Rapid test at a certified clinic. The result was negative. 7 weeks after possible exposure I again took an Oraquick Rapid test and the result was negative.
I then proceeded to take a Rapid finger pricking test at the 8 week mark and the result was also negative.
What are the chances that my test result changes to positive at the 3 month mark? Also what kind of people test positive later than 6 weeks?
Also, am I at risk if at the clinic where the finger prick test was done a little blood got on the finger the doctor had pricked after I had turned a doorknob? How long does HIV stay alive outside of the body exposed to air?
