A bid by a lawyer for Elizabeth Holmes to discredit a doctor testifying about inaccurate blood test results backfired Thursday during the felony-fraud trial for the Theranos founder.

Defense attorney Katie Trefz was cross-examining Dr. Mark Burnes, who testified that his patient in 2015 received two erroneous Theranos blood test results indicating possible prostate cancer. The patient had gone to an Arizona Walgreens for Theranos testing and received prostate-specific antigen (PSA) results more than 10 times his actual levels, Burnes testified.
