The indicators are derived from End‐of‐Cycle data from all of the RCPA Chemical Pathology programs that the laboratory is enrolled in. Three indicators are calculated:
- Participation Indicators – results returned, late and amended results
- All Analytes KPI (a ranking of the End‐of‐cycle %CV for all analytes)
- Indicator Analytes KPI (a ranking of the total error – precision and instrument based accuracy for selected clinically important analytes)
