U.S. regulators found serious shortcomings at a medical laboratory run by startup Theranos Inc., the latest in a series of setbacks for the highly valued blood testing startup founded by billionaire entrepreneur Elizabeth Holmes.

Deficiencies at Theranos’s lab in Newark, California, “pose immediate jeopardy to patient health and safety,” U.S. government regulators said in a letter to the company released Wednesday that demanded immediate changes at the lab and threatened the closely held company with sanctions.
