Startup medical testing company Theranos came under fire in October as the accuracy of its tests were called into question. The FDA has been investigating since then, and today more fuel was thrown on the fire by some former employees. According to The Wall Street Journal, both the FDA and the Centers for Medicare and Medicaid Services (CMS) each received a complaint from a different former employee. The FDA received notice that the study Theranos submitted to win the agency's approval for its herpes test was "tainted by breaches in research protocol." That's notable because so far that herpes test is the only one of Theranos' tests that has actually been approved by the FDA. Founder Elizabeth Holmes (above) has continued to deny any accusations claiming that Theranos' data is inaccurate.
