So, let me begin with what i believe was the worst decision I've made so far in my life. I had oral sex with a man of unknown status. no ejaculation, but i suspect precum. anyway, i have taken testing to a whole new level. I began with a NAT RNA HIV Test at 10 days, followed by an AB/AG 4th generation test at 10 days, 20 days, 30 days, and 47 days. So, i thought i was done? Well then i see the CDC respectfully state this : "An antigen/antibody test performed by a laboratory on blood from a vein can usually detect HIV infection 18 to 45 days after an exposure." SMH,,, so, can usually" is not to concrete in my opinion. throughout the HIV epedemic, I've heard 6 months, 3 months, 90 days,... as confirmative. but this whole 28 days, and now according to DR. HHH and Edwards, 6 weeks?
