Theranos is an American privately held health-technology and medical-laboratory-services company based in Palo Alto, California. It is under criminal investigation by federal prosecutors and the Securities and Exchange Commission.
Theranos developed a blood-testing device named Edison. The company said the device uses a few drops of blood obtained via a finger-stick, rather than vials of blood obtained via traditional venipuncture, utilizing microfluidics technology. By the summer of 2014, its founders had raised over $400 million from investors, valuing the company at $9 billion.
In October 2015, controversy surrounding the company's blood testing process arose after a report in The Wall Street Journal raised concerns about the accuracy of its Edison device. An independent U.S. government review by the Centers for Medicare and Medicaid Services reported inaccurate testing results and multiple deficiencies in sample handling during a recent inspection.
In June 1, 2016, Forbes revised its estimate of the company's net worth to $800 million.
On July 7, 2016, Theranos announced that it had received notice from the Centers for Medicare & Medicaid Services (CMS) regarding the revocation of its CLIA certificate. Sanctions include a prohibition of the owners and operators from owning or operating a lab for two years and a civil monetary penalty.
