> Current and former Safeway executives said Theranos missed deadlines for the blood-testing rollout. They also said several Safeway executives questioned the accuracy of results Theranos gave to Safeway employees tested at a clinic in the supermarket chain’s headquarters in Pleasanton, Calif.
> Theranos often drew the same employee’s blood twice, first with blood from a finger prick and then the traditional method of a needle in the arm, according to one former Safeway executive.
> The former executive said he worried that Theranos’s finger-prick process was still a work in progress. “If the technology is fully developed, why would you need to do a venipuncture?” this person said, using the term for a traditional blood draw.
> The concerns deepened when Theranos’s test results for several Safeway employees differed from the results the same employees got from other laboratories, according to the former executive. Another former Safeway executive confirmed those recollections.
> One Safeway executive got a frighteningly high result from Theranos on a test to gauge his prostate-specific antigen, according to two former Safeway executives. They said the test suggested that the executive had prostate cancer. Retesting by another lab came back normal.
