Blood-testing firm Theranos Inc. has confirmed it is under investigation by federal prosecutors and the U.S. Securities and Exchange Commission.
"The company continues to work closely with regulators and is cooperating fully with all investigations," a company spokeswoman said Monday.
Other agencies that have opened probes against the company include the State Departments of Health in Pennsylvania and Arizona, the Centers for Medicare and Medicaid (CMS) and the U.S. Food and Drug Administration.
The investigations by the Departments of Health of Pennsylvania and Arizona and the FDA have closed, Theranos said.
Earlier, Bloomberg reported the company was under investigation by the Securities and Exchange Commission and the U.S. Attorney's Office for the Northern District of California.
Walgreens Boots Alliance Inc. and the New York State Department of Health have received subpoenas in recent weeks seeking documents and testimony about representations made to them by Theranos, the Wall Street Journal reported Monday citing people familiar with the matter.
Walgreens Boots Alliance and the New York State Department of Health could not immediately be reached for comment.
The SEC and the U.S. Attorney's Office for the Northern District of California declined to comment.
