Quality Management Definitions


Quality Assurance (QA)
is the use of monitoring techniques, including inspections and audits, to promote confidence in laboratory results, to assure the quality of the data generated and to ensure compliance with accrediting bodies such as Clinical Pathology Accreditation (CPA).

Quality Control (QC)
is the use of techniques to reduce discord and discrepancy in results of measurement of the same quantity in the same material

External Quality Assessment (EQA) is the process whereby a laboratory’s analytical performance is assessed with respect to its peers using analytical material obtained from an external provider such as a United Kingdom National External Quality Assessment Scheme (UKNEQAS).
