Theranos results could throw off medical decisions, study finds

A study by researchers at the Icahn School of Medicine at Mount Sinai showed that results for cholesterol tests done by Theranos Inc. differed enough from the two largest laboratory companies in the U.S. that they could throw off doctors’ medical decisions. The Mount Sinai study was published online Monday in the peer-reviewed Journal of Clinical Investigation. The study concluded that Theranos’s results for total cholesterol were lower by an average of 9.3% than those produced by Quest and LabCorp.
