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.
