Impact of review method on turnaround time. Cases reviewed by telepathology only had a mean turnaround time (TAT) of 12 days (range, 1-28 days). Once uploaded, volunteers reviewed 92% of cases in <24 hours. Cases sent to BWH had a longer TAT, as expected, due to shipping logistics. Diagnoses of cases reviewed by telepathology or requiring additional work-up at BWH were similar, with the exception of CML (Figure 2).
