So Many Voided

Walgreens says that Theranos voided 11.3 percent of the blood test reports it generated for Walgreens customers, the Wall Street Journal reports.

The pharmacy chain filed a lawsuit against its former partner Theranos for $140 million in damages. Their partnership, which court records indicate dates back to 2010, came to an end earlier this year as the blood-testing company grappled with articles in the Wall Street Journal questioning its technology processes and regulatory issues — a Centers for Medicare & Medicaid Services inspection "condition-level deficiencies." Theranos then sent out tens of thousands of corrected lab reports before closing its labs last month to shift toward platform development.

Papers filed in that suit indicate that Theranos voided 31,000 test reports sent to Walgreens customers, the Journal reports, and that a Theranos official told Walgreens that it had voided 1,000 results from a blood-coagulation test performed at second lab. In addition, the lawsuit says that Walgreens learned of the voided test reports from media reports. The Journal further notes that the same month that Theranos told Walgreens that it voided 11.3 percent of the reports sent to Walgreens customers, Theranos told Bloomberg that it had voided less than 1 percent of its tests.
