SAN JOSE, CALIF. – A former laboratory manager at Theranos testified Tuesday that he left the company for one simple reason: the blood testing technology just wasn’t working.

Adam Rosendorff, a government key witness, spoke out on the fifth day of the fraud trial against ex-CEO Elizabeth Holmes.

“The pressure in the company was enormous to show the success of this technology,” said Rosendorff during the redirect check. “It came from above and penetrated research and development.”

He testified of his efforts to get Theranos executives, including Holmes, to address his concerns about the inaccuracy issues in the lab.

“She wanted to quickly expand the use of the Edison from the time it was introduced to the rest of my time with the company,” said Rosendorff of Holmes. The Edison was one of the company’s blood test analyzers.

Rosendorff testified that he left the company in November 2014 and was “very skeptical” of Edison and the company.

“I felt it was a matter of my integrity as a doctor not to stay there and support results that I essentially didn’t believe in,” said Rosendorff. “I realized that management was not being sincere when it came to redirecting resources to solving problems.”

Holmes faces twelve fraud charges related to allegedly belittling investors by hundreds of millions of dollars and misleading patients and doctors. She has pleaded not guilty and denies any wrongdoing. Holmes, once a child prodigy from Silicon Valley, claimed her startup Theranos could run hundreds of tests with just one prick of blood.

Rosendorff, who left Theranos seven years ago, said the preparation for the trial and the testimony had turned his life upside down.

“The stress of meeting with the government, the trip to a meeting with the San Diego government to the SEC in San Francisco,” said Rosendorff. “Essentially, I have this topic in my head. I have to relive very unpleasant experiences during Therano and media attention.”

The re-direction was followed by an intense and lengthy four day cross-examination by Lance Wade, a defense attorney for Holmes, who repeatedly tried to undermine Rosendorff’s earlier testimony.

In another case, to question his honesty, Wade pointed out some discrepancies in Rosendorff’s testimony compared to his testimony on the witness stand. Wade also asked Rosendorff about sensitive emails that he had forwarded to his personal Gmail account when he quit Theranos.

“Two pages of detailed health information for maybe 100 patients,” said Wade. “That’s a HIPAA violation, isn’t it?”

“I don’t know,” answered Rosendorff.

Rosendorff had previously testified that he had forwarded the company’s emails to himself in the event of a federal investigation and that he was considering filing a whistleblower lawsuit.

“They sent it so you can try to get money in this lawsuit,” said Wade.

“No, not at all,” answered Rosendorff.

“They also stole trade secrets,” said Wade.

“I don’t remember,” said Rosendorff.

Rosendorff’s testimony is expected to be completed on Wednesday.
