Theranos’ former lab director, Dr. Adam Rosendorff, told jurors on Friday that he quit the company because he “felt pressured to vouch for tests I did not have confidence in.”

The company’s management, he said, was not willing to perform proficiency testing that is required by federal law before clinical laboratories can run tests on patient samples. That, and a series of other issues, caused him to lose confidence in the company. “I came to believe that the company was more about PR and fundraising than patient care,” Rosendorff said.
