he had spoken to Carreyrou and also, under an alias, reported the company to the New York State Department of Health. Theranos claimed that the allegations were "factually and scientifically erroneous." Walgreens suspended plans to expand blood-testing centers in their stores following the report. At that time, the Cleveland Clinic announced that it would work to verify Theranos technology. Theranos fought back against the Journal investigation, sending lawyers after sources in the story, including Shultz, in an effort to stop them from providing information to the press. Former employees of reputation management firm Status Labs said that Theranos had hired the firm to discreetly erase mentions of the WSJs reporting from its Wikipedia article, despite the activity being a violation of the website's terms of use. Following the WSJ story, the history of FDA interactions with Theranos was scrutinized. The FDA had received a formal inquiry to look at Theranos blood test devices by the U.S. Department of Defense in 2012, before the devices were commercially available and did not require FDA approval. FDA inspection reports from 2014 and 2015 stated that its containers for blood collection were "not validated under actual or simulated use conditions" and "were not reviewed and not approved by designated individual(s) prior to issuance". In 2015, an FDA inspection resulted in multiple observed violations of FDA Title 21 Regulations. It was eventually revealed that the FDA had classified Theranos's device, called a nanotainer, as a Class II medical device, meaning that Theranos would need to use special labels, meet certain performance standards and perform post-market surveillance of the device. Theranos asserted that the nanotainer was a Class I medical device and therefore not subject to any regulatory requirements. After the 2015 inspection, Theranos announced that it would voluntarily suspend its tests apart from the FDA-approved herpes simplex virus (HSV-1) test. The Arizona Department of Health Services reported issues with the company's Scottsdale lab meeting regulations in September 2015. The reports were revealed in the Arizona Republic in November 2015. In January 2016 the Centers for Medicare and Medicaid Services (CMS) sent a letter to Theranos based on an inspection of its Newark, California lab in 2015, reporting that the facility caused "immediate jeopardy to patient health and safety" due to a test to determine the correct dose of the blood-thinning drug warfarin. Walgreens subsequently announced a suspension of Theranos blood tests from the Newark lab
