The External Quality Assessment Scheme (EQAS): Experiences of a medium sized accredited laboratory

Clinica Chimica Acta, 2015
We put forth our experiences of EQAS, analyzed the result discrepancies, reviewed the corrective actions and also put forth strategies for risk identification and prevention of potential errors in a medical laboratory.For hematology, EQAS samples - blood, peripheral and reticulocyte smears - were received quarterly every year.

The Role of External Quality Assessment (EQA) in Laboratory Services

The International Journal of Conformity Assessment
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.

Experience with an alternative form of samples for external quality assessment of urinary sediment (Visual Sample EQA)

Clinical Laboratory, 2013
Urinary sediment components are mainly unstable, especially in their original forms. This makes the use of such material in routine external quality assessment surveys (EQAS) almost impossible. The development of an alternative EQAS for urinary sediment using photomicrographs (visual-sample EQAS) is described here, together with results, improvements ...

Behind the Scenes of EQA – Characteristics, Capabilities, Benefits and Assets of External Quality Assessment (EQA): Part V – Benefits for Stakeholders Other Than Participants

Clinical Chemistry and Laboratory Medicine
Abstract External quality assessment (EQA) enhances patient safety through the evaluation of the quality of laboratory-based and point of care testing. Regulatory agencies and accreditation organizations utilize the results and the laboratory’s response to them as part of assessing the laboratory’s fitness to practice. In addition, where
