Table 1. Diagnostic and therapeutic recommendations generated by LabTest Checker (LTC) and specialist recommendations were categorized to assess LTC’s precision. Sensitivity for the emergency category was computed as the ratio of LTC’s correct emergency identifications to the physician’s emergency identifications: A / (A + B + C + D). Similarly, sensitivity for the urgency category was calculated as F / (E + F + G + H). Triage accuracy was calculated as (A + F + L + R) / total number of patients in the study. Triage safety as calculated as (A + E + F + J + K + L + N + O + P + R) / total number of patients in the study.
