The same way Theranos operated in Walgreens for awhile until the pseudotech finally was uncovered by the FDA and a WSJ reporter. The same way that LOCH/CDEX placed gizmos with the Missouri State Highway Patrol, a Puget Sound county, a bunch of realtors, and even the US Navy - before the gizmos were found to give totally erroneous and unreliable results and the LOCH/CDEX scheme fell apart.
That's how these pseudotech pennyscams roll - they tout baloney gizmos and place them to gett anecdotes and claim they are selling - to try to legitimize them until someone or some government agency unmasks the baloney - and then it all falls apart.
Really, Theranos is an example of such a scam run by a Stanford Ch.E. dropout - Elizabeth Holmes. She fooled a lott of people for awhile - until the gizmos were shown nott to work by the Wall Street Journal and the FDA and Medicare (CMS).
Study those examples - LOCH/CDEX and Theranos (a private company that will never become public - it will go extinct) and you will gett a flavor for how these pseudotech scams like MYDX operate.
