How is blood lab technology not a technically complex subject? Are you saying Carreyrou had direct expertise with it, or that _Bad Blood_ is an untrustworthy account?
It does indeed. The question you are asking leads me to believe you haven't read it. As a favor to the thread I will make this plain: drop everything else you're reading long-form and buy a copy of _Bad Blood_; it is fantastic. I didn't give a shit about Theranos. Until I got a couple pages into Carreyrou's book, that is.
