Hi, I had a possible exposure in April 24, 2014 and I got tested at 3 months and 6 months and it was negative. I want to donate blood at my local American Red Cross so I went and got another Hiv 1/2 on May 2015 and it was negative. I want to make sure I'm in the clear and if I can donate blood without harming anyone. Thank you. Ps why can't I post on the doctor forum?
