I am in no way defending inmate Elizabeth Holmes and her company Theranos, but I will point out that this is exactly the sort of work she was focusing on.
OncoRedox seems to be making progress and I know other companies are also discovering all kinds of disease with simple blood tests. I guess Elizabeth Holmes was a fraud. But I suppose these other companies have been given permission to succeed without being dragged into court.
She raised a lot of money. One major mistake she made was insisting the final step of multiple tests from a drop of blood, or nothing. Some of the very smart people working for her said they could make make tests with less blood. She would accept no iterations, only the final step.
