Deerfield, Ill.-based Walgreens alleges its former partner, Palo Alto, Calif.-based Theranos, voided 11.3 percent — or 31,000 — blood test reports provided to Walgreens customers, according to The Wall Street Journal.
The exact figure, which is new to the public, is part of a redacted version of Walgreens' recalled two years of test results against Theranos. The lawsuit, which seeks $140 million in damages, was filed under seal last week in a federal court in Delaware.
In May, after CMS found issues in Theranos' Newark, Calif. lab, the Silicon Valley startup recalled two years of test results, which Theranos publicly stated accounted for "tens of thousands of tests." Theranos told Bloomberg in June the voided or corrected tests accounted for less than 1 percent of total results it has provided patients.
Walgreens claims in the lawsuit the recall affected 31,000 test reports, and each report can include multiple tests, according to The Wall Street Journal. Theranos also allegedly recalled 1,000 tests conducted at its second lab, according to the report.
