In recent months, medical testing company Theranos has been slammed by media reports and federal inspections that say its blood testing devices don’t work. Amid the revelations, the company’s president stepped down, Theranos voided or corrected tens of thousands of blood test results, and Walgreens dumped its arrangement. Theranos now faces hefty federal sanctions, criminal charges, and several lawsuits from ex-customers. It has seen its valuation drop from $9 billion to just $800 million.
