Q01
How does LIMS IQ display Levey-Jennings charts?
Levey-Jennings charts plot saved QC results against the control lot's configured mean and ±1, ±2, and ±3 SD bands. Reviewers can filter by date, instrument, material, level, lot, and analyte; compare multiple instruments; open failed points with their rule detail; and export or approve the chart as a PDF.
Q02
Which Westgard rules does the QC module evaluate?
The built-in catalog includes 1-2s, 1-3s, 2-2s, 2 of 3-2s, R-4s, 3-1s, 4-1s, consecutive-value rules including 6x, 8x, 9x, 10x, and 12x, and a 7-point trend rule. Each control level lot can use its own selected rules, severity, and evaluation priority, and a failed result retains the specific rule it violated.
Q03
How are QC exceptions and corrective actions documented?
Reviewers can add comments to individual or selected QC results and exclude a documented outlier from charting with an ignore action and comment rather than deleting it. The result retains its status and failed-rule detail, while approved charts are archived as dated PDFs tied to the analyte, instrument, control lot, and review period.
Q04
How does QC integrate with patient result review and release?
Patient-result reviewers can open the QC results associated with a testing run, and batch review visibly alerts them when that run contains failed or non-passing QC. Affected samples can be placed on hold to block completion while the lab investigates. Whether to repeat, recalibrate, hold, or release remains governed by the laboratory's SOPs.
Q05
How are QC results reviewed and approved?
Pending QC results can be marked reviewed individually or in batches, with the reviewer and date recorded. After examining a Levey-Jennings chart for a selected period, a reviewer can approve it and archive the resulting PDF with its analyte, instrument, control lot, and date range for later inspection review.
