Which Epic process maps external lab results to internal test definitions?

• A. Lab/Test Mapping (Order Mapping)
• B. Care Gap Outreach / Population Health Outreach
• C. Referrals Management
• D. Break-glass

Answer: (A)

Lab/Test Mapping, often called Order Mapping, is the Epic process that links results from external laboratories to the internal test definitions used in the chart. When an outside lab sends a result, this mapping determines which internal test (or order) it belongs to, aligning codes, units, and interpretation rules so the result attaches to the correct patient and test. This ensures results display properly, support decision making, and feed accurate reporting. Without this mapping, external results can be misfiled or not linked to the right test at all. The other options involve outreach, referrals, or emergency access, not the task of translating and routing lab data into the internal test framework.
