Specimen Integrity and Quality Assurance in Clinical Laboratory Practice

Course overview

This course reviews the full specimen management process, including patient preparation, test ordering, specimen collection, labeling, documentation, transport, storage, stability, and chain-of-custody considerations. Participants will examine best practices for collecting and handling blood, urine, stool, swab, tissue, and body fluid specimens while reducing common risks such as hemolysis, clotting, contamination, leakage, insufficient volume, wrong container use, delayed transport, improper storage, and labeling discrepancies. The course also explores the relationship between specimen integrity, quality assurance, and quality control in clinical laboratory practice. Topics include internal controls, calibration, proficiency testing, equipment checks, standardized procedures, competency validation, and the use of quality indicators to identify process gaps. Participants will learn how specimen rejection criteria, recollection decisions, root cause analysis, corrective action, and preventive action planning support reliable testing and continuous quality improvement.
