They couldn't even do the basic stuff they fell back on after their groundbreaking machine failed to materialize, but they lied about it anyways and hacked COTS blood testing machines to accept fingerstick samples instead of the veinous draws they were designed to test --- which didn't work, and generated false results. They spent as much effort trying to contain stories and intimidate whistleblowers as they did on test accuracy. That'd be how I'd sum the book up.

It is a page-turner; extremely well-written.
