I wonder how this will come to market and how privacy will be protected. I know purchasing a test chip is not the same as confirming HIV positive but it is a data point, just as pregnancy tests are. If it's OTC do you have to consider how easy it is to track?
I could foresee these items being purchased in bulk by individuals. At the $1 price point Bachelors and Bachelorettes around the world might purchase these as frequently as Condoms.
