I was going through a health tech startup incubator at the time, and it became a bit of a meme where we'd poke fun at anyone who bought into Theranos. Some went as far as putting together a slide deck to debunk the claims about running labs on such tiny volumes of blood. This was when and where I learned about the heterogeneity of blood.

It was an obvious farce. If they had real tech they could have simply done a million comparative tests on the military/VA or at free clinics and showed the relative accuracy.

Yeah it was surprising that so many people with health care backgrounds fell for it.
