I tested negative with Nat testing and HIV 1/2 antibody after 14, 28, 63, and 101 days. I work for a tissue bank and sent my blood to their labs as a living donor. They used a 3rd generation antibody test and the Procleix Hiv 1 NAT test. Are these negative results conclusive after 101 days. I know the window is three and some say six months, but wouldn't one have a positive nat test after three months even if they had not produced antibodies?
