AI Delta Checks & Westgard QC Automation Software
Automated Westgard multirules (1-2s, 1-3s, 2-2s, R-4s), Levey-Jennings visual charts, and patient historical delta checks for clinical labs.
Automated Westgard Multirule Evaluation & Patient Delta Checks
AILS Cloud LIMS replaces manual quality control paper logs with real-time statistical evaluation. Evaluates incoming analyzer control runs against standard Westgard multirules, auto-plots Levey-Jennings charts, and performs intelligent patient historical delta checks to flag pre-analytical specimen errors.
Supported Westgard Multirules Engine
Warning Threshold
Triggers a soft warning when a single QC value exceeds 2 standard deviations from the lot mean.
Random Error Trigger
Rejects run when a single value exceeds 3 standard deviations. Immediately blocks analyzer result release.
Systematic Error
Triggers when 2 consecutive control runs exceed +2s or -2s, indicating reagent degradation or calibration drift.
Random Variance
Triggers when 1 control in a run exceeds +2s and another exceeds -2s, detecting high random dispersion.
Trend & Shift Detection
Identifies 4 consecutive runs exceeding 1s or 10 consecutive runs falling on one side of the mean.
Specimen Error Guard
Compares current results against historical patient baseline values to instantly flag IV fluid contamination or sample mix-ups.
