ABSTRACT

Precision and accuracy are the two pillars of quality in analytical testing process of a clinical laboratory. External quality assurance (EQA) holds a major share in shaping the analytical quality from accuracy perspective. But this depends on how laboratory perceives an EQA, understands it, and uses it effectively for inaccuracy assessment. External quality assurance has its own advantages and limitations, including the commutability of EQA sample, traceability of methods of comparison, the statistical procedure used for evaluation, etc. Our study discusses three brief case reports through which we have tried to explore the advantages and limitations of EQA.

Keywords: Clinical biochemistry, External quality assurance, Quality control, Traceability, Trouble shooting.
