I would have to expect there were at least a few brilliant scientists who worked there and contributed some momentum in this direction, and could be regaining some footing in legitimate operations now.

Theranos was claiming they were already delivering the full spectrum of tests when the promise is still not fullfillable.

Alternatively, realistically focusing on a single miniaturized test or two until you get consistency with the established reference instruments could provide the foundation for a worthwhile investment by comparison.
