External Quality Assessment (EQA) plays a critical role in safeguarding the accuracy, reliability, and clinical utility of genomic testing. While its immediate value in identifying errors and benchmarking performance is well recognized, the long-term impact of sustained EQA participation on laboratory quality and improvement is less well studied.
EQA contributes to quality assurance by:
• Monitoring laboratory performance and test accuracy
• Detecting and reducing critical analytical and interpretive errors
• Supporting continuous quality improvement through feedback and benchmarking
This study investigates the utilization of longitudinal EQA performance data, highlighting its role in not only evaluating compliance but also fostering significant and lasting improvement in genomic testing laboratories over time.
