What was your risk event?
The odds of anyone getting 2 false negatives in a row are astronomical. I also suspect you were reading older studies.
I have been reading the clinical studies done for the Oraquick stating the 91.7% accuracy rate for positive tests. It states "Of the 10 false negatives (2.08%) observed in this study, all were known HIVpositive individuals." Would this mean that these 10 people could've been on ART, therefore they showed up negative? Or would the use of ART not matter with oral fluid?
