Study Notes

Laboratory Quality Management System

Laboratory processes can be categorized into pre-examination, examination, and post-examination phases, also known as pre-analytic, analytic, and post-analytic processes.
The path of workflow begins with the patient and ends with reporting and results interpretation.
A laboratory quality management system ensures accuracy and reliability of testing by detecting errors at each phase.

Pre-Examination Phase

This phase includes patient preparation, sample collection, sample receipt and accessioning, and record keeping.
Errors in this phase can produce poor laboratory results.

Examination Phase

This phase involves quality control testing and laboratory processes.
Laboratory processes must be carried out correctly to assure accuracy and reliability of testing.

Post-Examination Phase

This phase includes reporting and results interpretation.
Errors in this phase can also produce poor laboratory results.

Quality Management Essentials

Documents and records are essential for quality management.
Information management is critical for ensuring accuracy, confidentiality, and accessibility of laboratory results.
Occurrence management is necessary to detect and handle errors or events that should not have happened.

Assessment and Process Improvement

Assessment is a tool for examining laboratory performance and comparing it to standards or benchmarks.
Process improvement is a continuous goal in a quality management system.
Customer service is essential in laboratory practice, and customer feedback is necessary for making improvements.

Facilities and Safety

Facilities and safety management involves security, containment, and safety policies and procedures.
These factors are critical for preventing unwanted risks and hazards in the laboratory.

Definition and Importance of Laboratory Quality

Laboratory quality is defined as accuracy, reliability, and timeliness of reported test results.
Inaccurate laboratory results can have significant consequences, including unnecessary treatment, treatment complications, and poor patient outcomes.
