Emphasis on attempt. After failing to produce their own reagents and hardware, Theranos pivoted to using off-the-shelf Siemens hardware and reagents (purchased through a shell company) and dramatically diluting the blood samples to make good on the "single drop of blood" customer promise. This would've been an impressive feat of reverse engineering, software eating the world, IF IT WORKED. But it didn't. Results couldn't even pass internal audits and the FDA forced Theranos to invalidate ~1 million test results when they found what was going on.
