Your test result at six months of "0.11" is "nonreactive. That means you are definitively and conclusively
hiv negative. The "index value" (also called the "signal-to-cutoff ratio") is a technical term having to do with how this type of hiv-antibody test is conducted. If your results were 0.04, 0.05, 0.06 or anything less than 0.25 then you do not have hiv. There is no test that is 100% correct for hiv or for any illness. The time at which you take a test is related to its level of accuracy
thus you have no hiv.
