A false negative can happen with any test taken to early. OI doesn't happen until a person infected with HIV has a CD4 count below 200. So yes, that is during advance HIV infection and usually only happens with people not taking HAART or having a resistance problems with the medication that they are on. People with CD4s that low are always put on antibiotics to help prevent OIs. I've been on antibiotics w/HAART for the last three years. Once your CD4s stay above 200 for three consecutive months the antibiotics will be discontinued.
I should have clarified the false negative question. I automatically presumed that one would wait at least until 90 days. Also, I did find some information elsewhere that says this about the Home Access test.
"Clinical studies have shown that the approved HIV test system is able to correctly identify 100% of known positive blood samples, and 99.5% of HIV-1 negative blood samples."
