There was a time when Walgreens championed Theranos' blood tests and offered them at "wellness centers" in its stores. That was before it came to light that Theranos' tests were faulty, leading to a bitter breakup between the two companies. Now, according to Bloomberg, Walgreens has agreed to pay $44 million to settle a class action lawsuit brought by customers who received flawed Theranos blood tests through its centers in Arizona and California.
