| 1. Introduction to Quality Assurance (QA) Definition of Quality Assurance vs Quality Control (QC) Importance of QA in laboratory operations Role of QA in ensuring reliable and valid results Link with ISO/IEC 17025 requirements 2. Quality Management System (QMS) Overview Components of a laboratory QMS Documentation structure: Quality policy Procedures (SOPs) Work instructions Records Process-based approach 3. Quality Control Techniques Internal Quality Control (IQC) External Quality Control (EQC) Use of control samples Duplicate testing and blind samples 4. Statistical Quality Control Tools Mean, standard deviation, coefficient of variation Control charts: Levey-Jennings charts Shewhart control charts Trend analysis and outlier detection 5. Control Charts (Core Concept) Monitoring performance using standard scores (Z-scores) Setting control limits (±2σ, ±3σ) Identifying out-of-control conditions 6. Method Validation & Verification Validation parameters: Accuracy Precision Specificity Linearity Range Detection limits Difference between validation and verification 7. Proficiency Testing (PT) & Inter-Laboratory Comparison (ILC) Purpose and importance Participation requirements Interpretation of results (Z-score evaluation) Corrective actions for poor performance 8. Measurement Traceability Concept of traceability to SI units Calibration of instruments Use of certified reference materials (CRMs) 9. Measurement Uncertainty in QA Role of uncertainty in assuring result quality Integration with QA practices Impact on decision-making 10. Quality Assurance in Sampling Sampling plans and techniques Representativeness of samples Sample handling and preservation 11. Data Integrity & Record Management Accurate data recording Prevention of data manipulation Electronic data management systems Traceability of records 12. Internal Quality Audits Role of audits in QA Monitoring compliance Continuous improvement 13. Non-Conformities & Corrective Actions Identification of deviations Root cause analysis Implementation of corrective actions Preventive measures 14. Risk-Based Thinking in QA Identifying risks affecting quality Risk assessment tools Mitigation strategies 15. Continuous Improvement Techniques PDCA (Plan-Do-Check-Act) cycle Six Sigma basics Lean laboratory concepts Performance indicators (KPIs) 16. Documentation & Reporting QA reports Control charts documentation Validation reports SOP compliance 17. Common Challenges in QA Inconsistent procedures Poor training Inadequate documentation Failure to monitor trends 18. Practical Training Activities Creating control charts Analyzing QC data Method validation exercises Case studies on QA failures ✔️ Key Takeaways QA ensures accuracy, reliability, and credibility of lab results Statistical tools are essential for monitoring performance Continuous improvement is a core principle of QA Strong documentation supports compliance and traceability |
