Study Notes
External Quality Assessment (EQA)
- EQA is a systematic method for objectively evaluating laboratory performance via an external agency or facility.
- It serves multiple purposes, including identifying areas requiring improvements, highlighting training needs, and providing early warning for systematic problems.
- EQA provides objective evidence regarding the quality of testing processes across different test sites, facilitating performance comparisons.
EQA Methods
- Proficiency Testing (PT): Regular interlaboratory comparisons assessing analytical laboratories and personnel performance.
- Rechecking: Involves random sample collection to eliminate bias and ensure statistical significance; resolves discrepancies effectively.
- Retesting: Conducted by reference laboratories on non-blinded dried blood spots or serum samples to derive statistically meaningful results.
- On-site Evaluation: Conducted for an accurate depiction of laboratory practices and to assist with identified issues.
Proficiency Testing Process
- A structured procedure where PT samples are sent to laboratories regularly.
- Following analysis, laboratories receive a performance report which outlines their results.
- Laboratories must take corrective actions based on the feedback received from the PT report.
Importance of EQA
- It is crucial for measuring laboratory performance and facilitating continuous improvement.
- Compliance with ISO 15189 standards mandates EQA processes for accredited laboratories, ensuring adherence to quality requirements.
