Laboratory quality, process improvement and operational management. https://ayuslab.com/articles en ISO 15189 works best when its quality requirements are built into everyday laboratory processes, not treated as paperwork for audits. Routine controls such as sample identification, QC, result review, critical communication, and report correction create reliable evidence. Continuous monitoring, traceability, staff competence, and management review help maintain quality and improve laboratory operations.

A proper audit trail records what changed, why, when, and who authorised and communicated the correction. Version control and traceability help ensure the updated report is clear, accurate, and safely communicated.

Clear rejection criteria help laboratories identify unsuitable samples, manage exceptions, and ensure proper recollection. Tracking rejection trends helps identify recurring problems and improve the overall specimen collection and handling process.

A closed-loop process includes communication, read-back, documentation, and escalation when contact or acknowledgement fails. Clear procedures and monitoring help laboratories improve patient safety and ensure reliable critical-result reporting.

They help detect possible specimen, analytical, identification, or reporting issues without assuming the result is wrong. Proper validation, documentation, and professional review are essential for using delta checks effectively.

They cover pre-analytical, analytical, and post-analytical activities with clearly defined measures and responsibilities. Regular trend review helps laboratories investigate issues, take corrective action, and improve overall quality.

A failed QC does not automatically mean every patient result is wrong—it signals that the analytical system requires documented review and evidence of recovery. A LIMS can support traceability, alerts, corrective-action records, result review, and audit history, while professional judgement remains essential for investigation and patient-result decisions.

Approved QC rules and professional judgement are used to decide whether a result requires investigation or corrective action.

Together, they provide complementary evidence of analytical performance and help laboratories identify, investigate, and address potential problems.

It uses control materials and defined review processes to detect changes that could affect patient results and supports timely investigation and corrective action.
