Study Notes

Overview of Quality Management System

Defined by ISO and CLSI as "coordinated activities to direct and control an organization with regard to quality."
Includes all aspects of laboratory operations: organizational structure, processes, and procedures to assure quality.

Importance of Quality in Laboratory Operations

Each laboratory procedure must be executed correctly to ensure accuracy and reliability of results.
Errors at any testing phase can lead to poor outcomes, necessitating error detection methods throughout the testing cycle.

Testing Phases

ISO standards classify laboratory processes into three categories:
- Pre-examination (pre-analytic)
- Examination (analytic)
- Post-examination (post-analytic)
The entire operation in testing is referred to as the Path of Workflow, which spans from patient interaction to result interpretation.

Factors Ensuring Laboratory Quality

Affected by the laboratory environment, quality control procedures, effective communication, thorough record-keeping, skilled personnel, and reliable reagents and equipment.
Components of quality include accuracy, reliability, and timeliness of test results.

Role of Quality Management System

A QMS does not eliminate errors but facilitates error detection and corrective actions.
Ensures a systematic approach to managing laboratory quality operations.

Quality Essentials by CLSI

CLSI identifies twelve quality essentials that guide laboratories towards achieving quality operational standards.
Laboratories must establish comprehensive systems managing both the quality of results and adherence to relevant standards.

Systematic Approach

QMS should encompass all laboratory operations, including the organizational structure and testing processes.
Correct execution of processes across pre-analytical, analytical, and post-analytical phases is crucial for maintaining accuracy and reliability.
Neglecting quality essentials during any testing phase risks generating inaccurate or unreliable results.
