Das testified that he told Holmes about women’s blood showing significant levels of prostate-specific antigen — a protein typically found only in trace elements in women — because those results provided an “easily digestible” example of Theranos’ machines “propensity” for errors. Holmes responded by providing Das with “an article or two” describing a rare phenomenon of breast cancer tumors in women producing the protein.
