Theranos’ False Promise: Why It’s Just Impossible to Do 70 Tests with One Drop of Blood

Originally aired on 4/25/2019

Dr. Oz shows us just how wrong Theranos’ promise really was — with a live demo. Jon R. Cohen, MD, the executive chairman of BioReference Laboratories, reveals how much blood you’d really need to perform 70 tests. (It’s a lot more than one drop!)

Guests: Meek Mill , Michael Rubin , John Carreyrou , Erika Cheung
