OREANDA-NEWS. February 01, 2016. In light of the letter dated Jan. 25 from the Centers for Medicare and Medicaid Services (CMS) to Theranos, Inc., Walgreens said today that it has informed Theranos that it must immediately cease sending any clinical laboratory tests provided through Theranos Wellness Centers at Walgreens to the Theranos lab in Newark, Calif., for analysis.

In addition, Walgreens is suspending Theranos laboratory services at its Palo Alto, Calif., store, effective immediately.

Walgreens informed Theranos that tests collected at 40 Theranos Wellness Centers located at stores in Arizona must be sent only to Theranos’ certified lab in the Phoenix area or to an accredited third-party lab for analysis. No patient samples will be sent to the Newark lab until all issues raised by CMS have been fully resolved.
