External quality assessment (EQA) is an important tool in laboratory services, ensuring the accuracy, reliability, and consistency of diagnostic test results. In an EQA program, an external body distributes unknown samples to participating laboratories, which analyze them and report their results for comparison with those of peer institutions. This process enables laboratories to identify errors, monitor performance trends, and implement corrective measures. This article outlines the concept, process, importance, and challenges of EQA and highlights its role in supporting patient safety and healthcare quality.
