The court limited Holmes-Parloff interview excerpts and addressed the scope of Tompkins's testimony. Burnes and Ellsworth traced sharply divergent PSA results, while Parloff testified about Holmes's representations concerning Theranos's test range, analyzers, military use, and pharmaceutical reports before facing questions about reporting ground rules and note reliability.
Full day summary
Before the jury entered, the court addressed excerpts from Roger Parloff's interview with Elizabeth Holmes. It admitted a limited passage under Rule 106 for a state-of-mind purpose related to intent, excluded the remainder, and rejected a separate patents-and-trade-secrets excerpt as hearsay as presented while leaving open possible reconsideration. The court also limited Erin Tompkins to testifying about what she told her physician, not what the physician told her. On cross-examination, Tompkins described her later HIV test, her limited memory of a second Theranos conversation, and her confusion about the components of her 2015 result; the court admitted one page of a CDC testing algorithm but barred a question lacking foundation.
Physician Mark Burnes testified as a PSA-testing expert about patient Mehrl Ellsworth's Theranos results of 26.1, 1.71, and 22.8, followed by a traditional-method result of 0.95. Burnes said the first result did not fit Ellsworth's prior pattern, requested repeat testing, and considered it invalid; corrected Theranos reports later voided the first and third results. On cross-examination, he acknowledged Theranos's convenience, his earlier hope that it would succeed, its apparent effort to investigate the problem, and his lack of personal knowledge about what Holmes knew before a June 2015 email. Ellsworth then confirmed that his prior PSA values had never exceeded 2 and traced the four Theranos tests, including the final venous draw.
Parloff described the reporting behind his 2014 Fortune profile and testified that Holmes represented Theranos as offering a broad test menu, proprietary testing, high accuracy, military use, and pharmaceutical validation. He said she did not disclose before publication the broader use of conventional analyzers, narrower device capabilities, or accuracy and reliability problems, and did not explain Theranos's role in preparing reports carrying pharmaceutical-company names. According to Parloff, Holmes first described third-party analyzers in 2015 as a new practice for esoteric tests and later estimated that the proprietary device could perform 50, 60, or perhaps 70 tests. Cross-examination addressed Theranos's trade-secret restrictions, off-the-record ground rules, Parloff's sources, and the reliability of his notes. He acknowledged using leading questions in an unrecorded Siemens exchange, discarding the underlying handwritten notes under Fortune's retention policy, and a discrepancy about when he rediscovered that exchange. Several audio excerpts were played off the record, so their contents were not available in the proceeding transcript.
