The Elizabeth Holmes Trial: Former Product Manager Details Shortcuts as Devices Failed

Mr. Edlin is the 15th witness to take the stand in Ms. Holmes’s trial, where prosecutors are trying to prove that she defrauded patients and investors about what Theranos’s finger-prick blood-testing machines were capable of accomplishing.

Mr. Edlin described to jurors how part of his job included giving tours of the company headquarters and demonstrations of Theranos’s blood-testing devices to important visitors, including investors.

Those tours followed a path scripted by Ms. Holmes, he said, and often included using a partition to block certain Theranos devices from view. In one instance, he recalled, he was asked to help bring 10 to 15 Theranos machines into a room next to the lab and set them up as if they were in use.

The company had several backstops to use if live demonstrations of Theranos devices didn’t go as planned, he said. Often, blood would be drawn from a finger prick in one room where the device and visitor were located, but would then get tested in Theranos’s lab.

The machines also had what was called a “demo application” that would prevent the device’s screens from showing an error even if it wasn’t working, he said, which was often installed on the machines being shown to guests.

During a demonstration in June 2013, he said, blood tests were run both in New York during a demonstration and again back in the California lab. The results differed, he said, and jurors saw emails discussing what to do.

“The discrepancy will be a problem. We need to see if we can correct for it,” Ms. Holmes wrote in an email to staffers.

Daniel Young, a high-level Theranos employee, asked Mr. Edlin to change the reference ranges on two results, which are numbers given as a benchmark so patients know if their result on a given test is higher or lower than what is typical.

In response to questioning by prosecutors, Mr. Edlin said the outcome of the change was making what appeared to be a low result on a test look normal.

Mr. Edlin’s work at Theranos was far-reaching, including helping the company implement its testing centers in

stores and working with Theranos’s marketing and public-relations departments. He testified that at one point, six friends from Duke all worked at the company.

Before Theranos went live with patient testing in Walgreens, it was preparing to launch a website. Jurors saw an email sent by a law firm specializing in food-and-drug law laying out pages of changes they suggested be made to lofty claims Theranos planned to make.

Those included watering down lines saying Theranos technology was “more precise,” “faster and easier” and had the “highest levels of accuracy.” They also requested substantiation for claims that Theranos had “unprecedented speed and accuracy” and used “1/1,000 the size of” a typical blood draw.

In his final years at Theranos, Mr. Edlin reported directly to Ms. Holmes, speaking with her daily. “She was in the office all the time really,” he said, from “early morning to late in the evening,” including on weekends.

He echoed testimony from other Theranos staffers that information at the company was kept siloed. “Information that I needed to know relative to the work I was doing I could seek,” he said in court, “but aside from that I had no need to ask about it and shouldn’t ask about it.”

Unlike other former employees who have taken the stand, Mr. Edlin hasn’t testified about any concerns he had about Theranos for the majority of the time he worked there.

Even so, he said it was time to move on in 2016 in part because he was going to business school, but also because, a year after the Journal’s reporting, “I no longer believed, based on what I was seeing, that the company was capable of standing behind the claims it had been making about the technology.”
