Results of clinical testing obtained from laboratories or testing sites at or near the point of care must be as accurate as possible as they have a direct impact on care and treatment, prevention, and control of diseases. Testing consists of pre-examination, examination, and post-examination processes, which require strict implementation of a quality management system.

The term “external quality assessment” (EQA) is used to describe a method/process that allows testing conducted by a laboratory, testing site or individual user to be compared to that of a source outside the laboratory – of a peer group of laboratories or a reference laboratory or testing site.

This manual describes some of the strategic, managerial, financial, technical and scientific aspects to be considered in establishing a national EQA programme for clinical laboratories and other testing services at all health care levels.
