All expect results that are accurate and obtained in an efficient and effective manner, within a suitable time frame and at acceptable cost. There are different ways of achieving the end results, but compliance with International Organization for Standardization (ISO) 15189, the international standard for the accreditation of medical laboratories, is becoming progressively accepted as the optimal approach to assuring quality in medical testing. We present recommendations and strategies designed to aid genetic testing laboratories with the implementation of a quality management system, including key aspects such as document control, external quality assessment, internal quality control, internal audit, management review, validation, as well as managing the human side of change. The focus is on pragmatic approaches to attain the levels of quality management and quality assurance required for accreditation according to ISO 15189, within the context of genetic testing. Attention is also given to implementing efficient and effective quality improvement.

EuroGentest is an EU-funded Network of Excellence that intends to To support laboratories working towards accreditation and to structure, harmonize and improve the overall quality of genetic testing improve the understanding of quality assurance (QAu), interactive services.7 The project consists of five units addressing all aspects of workshops were developed, within the framework of the EuroGentest genetic testing: quality management, information databases, public Network of Excellence (EUGT NoE, FP6-512148, http://www. health, new technologies and education. Among the key outcomes of eurogentest.org).6 A successful format was achieved by integrating the past 5 years are the development of a programme of interactive expertise in both laboratory and quality management, and in learning workshops on quality management for people working in genetic and change management. Topics include accreditation, QAu, internal testing laboratories; the expansion of EQA schemes; a QAu database of audit, diagnostic validation, internal quality control (IQC), external validated data on EQA participation and accreditation, available in the quality assessment (EQA), management review (MR), software Orphanet database; and a series of information leaflets in different support for quality systems (QSs) and change management.
