In 2012 Safeway invested $350 million into retrofitting 800 locations with clinics that would offer in-store blood tests. After many missed deadlines and questionable results from a trial clinic at Safeway's corporate offices, the deal was terminated in 2015. In 2013, Theranos partnered with Walgreens to offer in-store blood tests at more than 40 locations. Although Theranos blood tests were reportedly used on drug trial patients for GlaxoSmithKline and Pfizer, both companies stated that there were no active projects with Theranos in October 2015. In June 2016, Walgreens terminated its partnership with Theranos. In November 2016 it filed suit against Theranos in federal court in Delaware for breach of contract. In June 2017, Theranos reported to investors that the suit, which originally sought $140 million in damages, was settled for less than $30 million.

In March 2015 the Cleveland Clinic announced a partnership with Theranos to test its technology and decrease the cost of lab tests. In July 2015, Theranos became the lab-work provider for Pennsylvania insurers AmeriHealth Caritas and Capital Blue Cross.
