Laboratory Quality Assurance and Accreditation
Quality Control Procedures
Quality control (QC) plays a vital role in ensuring the reliability of laboratory test results. Internal quality control (IQC) involves daily checks to assess the precision and accuracy of the tests, while external quality assessment (EQA) assesses the laboratory's performance against industry standards via proficiency testing.
ISO/IEC 17025 Standards
ISO/IEC 17025 sets the standard for competence in testing and calibration laboratories. It requires a comprehensive quality management system (QMS) that includes QC, personnel training, and environmental monitoring. Compliance with ISO/IEC 17025 is crucial for credibility and recognition by regulatory authorities.
Proficiency Testing
Proficiency testing (PT) is a form of EQA that involves sending a laboratory samples with known properties to assess their ability to correctly identify and report the results. PT is essential for maintaining competence and improving performance.
