> So far not a single investor has claimed that their DD team did not have access, that their DD team was competent to do the job in the first place and that the technology as evaluated was sound.

This doesn't tell us one way or the other if DD took place and if so, the scope.

> The technology enabled that. Without the tech that failed to materialize and is not the core of the innovation that Theranos represents.

The technology is orthogonal to their regulatory machinations. They could have developed an in-house ELISA (or whatever, something more conventional) and made similar regulatory plays as they did with their microfluidics system.

> Yes, but if you run enough samples then you should converge at something amounting to statistical equivalence. If that doesn't happen then either one of the tests is invalid.

That handwaves over the complexity of the study, which goes to my point that your trivial and foolproof experiment is neither. A proper one probably needs a CRO. For a sizable investment it could be worthwhile, but I think you've underestimated the scope of your proposal.

> As are secrecy, refusing access to labs, not providing full details on the technology under NDA, refusing to run a sufficient number of blind tests at the request of the DD team.

Some of that in context isn't outside the behavior of other medical technology companies. It would be negligent to allow someone that wasn't with the government to walk through my lab without making some sort of arrangement ahead of time, and certainly under no circumstances unsupervised. I also have withheld key technical details to someone running DD despite having an NDA because NDAs cost money I didn't have to enforce if needed. The last item about testing is certainly a huge red flag, but [citation needed] if you're saying that Theranos did it (I find it possible to believe, but I haven't read that until your comment).

> If that were true that would mean they had working technology, which they did not have at all.

That might be an overstatement? I've followed this case closely, and I've had a very difficult time understanding what was claimed to work and did, what was claimed to work and didn't, what wasn't claimed by Theranos but is rumor transmuted into fact by the internet, etc. I've been operating under the assumption that the technology did work under controlled conditions and had problems when scaling up, but that is speculative on my part. I'm not aware of any scientific or medical reasons to believe that their platform cannot work, I am however aware of medical reasons to expect challenges to overcome (off-hand, sample volume, collection site), have violent disagreement as to the importance of consumer-intiated testing, etc. Unlike uBeam, there doesn't seem to be fundamental reasons to believe that Theranos' platform could not work and microfluidics being known to the art is supportive. If there are fundamental reasons that the technology cannot work, or if you have good hard sources for what Theranos had working and when, please do share!

> Even for some of the most basic testing they had to fall back on equipment supplied by others and this would have definitely turned up in a real DD, barring magic I don't see how they could have gotten away with it in any realistic setting.

"That's a great observation. It's true we do use conventional equipment for some basic tests and we are up front about that with our strategic partners, and it's simply because it's cheaper to run basic tests on the conventional equipment than on the Edison 1.0. Rather than waste money by insisting all testing run on Edison 1.0, we actually take the savings from running the basic tests on the conventional equipment, and roll that into the development budget for Edison 2.0 which we project will handle 98% of our full panel. Being intimately familiar with conventional equipment has other benefits: it's an important element of our development process to help us to better understand how we can deliver value-based differentiators on Edison 2.0." (or something like that) If they're willing to lie, they can spin a nice yarn and back it up with phony data. It won't fool everyone, but they don't need to fool everyone.
