About

Testifying about a patient's conflicting serial HCG reports, Zachman explained how the Theranos results affected her pregnancy assessment and why the correction and follow-up study did not restore her confidence. Cross-examination narrowed her expertise to clinical interpretation rather than assay science and examined the limited number of other questioned results.
