Study Notes
Introduction to Quality Control (QC)
- Quality Control (QC) in a lab is a systematic process ensuring accurate, reliable, and reproducible test results.
- QC includes steps, techniques, and tools to monitor, evaluate, and maintain consistency and reliability.
- Laboratory QC is vital for ensuring test validity, meeting regulatory standards, and maintaining lab credibility.
- Quality assurance includes assessment/monitoring, program development, and quality improvement/control.
Importance of Quality Control in Laboratories
- QC's main goal is ensuring accurate and reproducible test results
- This is critical in clinical diagnostics, pharmaceuticals, environmental testing, and research.
- Laboratories should adhere to standards like Good Laboratory Practices (GLP), ISO/IEC 17025, and Clinical Laboratory Improvement Amendments (CLIA).
- QC helps with compliance and meeting accreditation needs.
- Accuracy of test results in clinical labs impacts patient care, treatment decisions, and public health.
- QC identifies errors in lab processes like sample collection or analysis.
- Identifying and addressing issues early minimizes waste and re-testing.
Key Concepts of Quality Control
- Accuracy is how close a measured result is to the true value.
- Precision is how reproducible results are under the same conditions.
- Quality Control (QC) involves procedures and actions to monitor and verify the accuracy and precision of lab results.
- Quality Assurance (QA) is the overall management system ensuring predefined quality standards are met.
- Standard Operating Procedures (SOPs) are essential for QC.
- SOPs are written documents that instruct on proper methods and procedures for tests or analyses.
Types of Quality Control in Laboratories
- Internal Quality Control (IQC) includes regular processes and checks within the lab.
- IQC's aim is to monitor and maintain the quality of results generated.
- Control samples with known results are used to test lab equipment and procedures.
- Equipment calibration is regularly done to ensure accuracy.
- Proficiency testing involves analyzing blinded samples internally and comparing results to known values.
- External Quality Control (EQC) involves participating in external proficiency testing programs.
- Labs send results to an external agency for accuracy evaluation and comparison with other labs.
- Proficiency Testing Programs (PTPs) involve a lab submitting results to an external body for comparison with other labs.
- Inter-laboratory comparisons involve comparing results from different labs to identify discrepancies or biases.
Benefits of Quality Control in laboratories
- Ensures consistent and trustworthy test results.
- Helps labs meet local and international standards and maintain certifications.
- Builds trust with clients, especially in medical and diagnostic labs.
- Reduces errors, re-testing, and waste, leading to lower operational costs.
- Supports ongoing refinement of processes, procedures, and staff training for better outcomes.
