The onslaught of bad news for Theranos, the start-up laboratory services company plagued with troubles since last October, continued this week with a new round of reports and press coverage. First, on March 28, the Journal of Clinical Investigation published an article that found that Theranos’ tests tended to produce more irregular results than those of two other laboratory services companies. Then, on March 31, an inspection report by the Centers for Medicare and Medicaid Services was released, revealing numerous problems at Theranos that led to quality control problems, possibly leading to inaccurate test results for patients. The article and report both raise additional questions about Theranos’ claims and long-term viability – a steep letdown from early hype about the company, which promised to revolutionize the laboratory testing industry. The story of Theranos’ troubles highlights how scientific flaws and regulatory mishaps can lead to serious problems for companies seeking to innovate in the health sciences space.
