Walgreens threatens to pull out of Theranos partnership: WSJ

(Reuters) - Walgreens Boots Alliance Inc , the largest U.S. drugstore chain, threatened to terminate its relationship with Theranos Inc unless the blood-testing company quickly fixes the problems found by federal inspectors at its laboratory in California, the Wall Street Journal reported. The drugstore chain gave the warning in a letter to Theranos late last month, the Journal said, citing people familiar with the matter. A spokesman for Walgreens declined to comment.
