SummaryDuring the 20th century understanding for quality has changed and international and national requirements for quality have been published. Therefore also medical branches started to establish quality management systems. Quality assurance has always been important for medical laboratories. Certification according to the standard ISO 9001 and accreditation according to the standard ISO 17025 have been the proof of fulfilling quality requirements. The relatively new standard ISO 15189 is the first standard for medical laboratories. This standard includes technical and management requirements for the medical laboratory. The main focus is the proof of competence within the personnel. As this standard is accepted throughout the European Union an increase in accreditations of medical laboratories is predictable.

During the past ten years many activities have taken place in medical laboratories to harmonized the quality systems and accreditation activates. At that time, different approaches were followed in European countries concerning the demands for a quality system in a medical laboratory, and for the choice between certification or accreditation. Also, the working group on accreditation, of the European Communities Confederation of Clinical Chemistry (EC4) with as official name WG on Harmonization of Quality Systems and Accreditation was formed. From the start, the European Diagnostic Manufacturers Association (EDMA) was invited to participate, because harmonisation of quality systems and accreditation is of common interest. A crucial point in the quality revolution in medical laboratories is broad-based awareness of total quality management throughout the diagnostic business from manufacturers to laboratories to physicians and patients. In fact, the quality of laboratory tests largely depends on the products supplied (industry) and on quality management (laboratory management). Manufacturers recognize that accreditation gives high value to medical laboratories. However, while clinical laboratory practice is the responsibility of laboratory professionals, the in vitro diagnostics industry has a major role to play as the supplier of high quality goods and services, as training, scientific services, etc. On the other hand, the IVD industry is directly affected by accreditation schemes, and by the changes in laboratory practice and requirements that they initiate. The IVD Directive is a new example of legislative regulation that obliges the manufacturer (those who are not ISO 9000) to implement a quality management system. At the same time, the IVD Directive includes validation of products by competent laboratories, for ?sensitive? products. In fact, clinical laboratories should be assisted by manufacturers that provide reliable documentation, standard information for use, calibration procedure, performance checks and guide for preventive maintenance. The IVD Directive (EC 98/79) is released on December 1998, it is effective since June 2000 and final implementation is obliged from December 2003. IVDD shall ensure that only one safe and effective products will be sold in the European Union (EU), and just a single product approval is required to sell the products throughout the entire European Union. Official mark for products in conformity with the IVD Directive is CE label.

This chapter deals with issues of quality management and quality assurance in medical laboratories. Basic terms and their role in quality assurance in laboratory examinations are analyzed and discussed. Clarifications on certification and accreditation are given with a comprehensive analysis of the procedures they refer to and their implementation for particular tasks. The implementation of the international standard ISO 15189 is presented with reference to some recent developments. The chapter has been prepared to help medical laboratories in an introductory understanding of quality assurance issues and encourage them to proceed with the implementation of the standard ISO 15189 and not as a detailed guide. Some practical considerations rising from the experience of a small country such as Cyprus are also discussed.

AbstractThe 2014 Milan Conference “Defining analytical performance goals 15 years after the Stockholm Conference” initiated a new discussion of issues concerning goals for precision, trueness or bias, total analytical error (TAE), and measurement uncertainty (MU). Goal-setting models are critical for analytical quality management, along with error models, quality-assessment models, quality-planning models, as well as comprehensive models for quality management systems. There are also critical underlying issues, such as an emphasis on MU to the possible exclusion of TAE and a corresponding preference for separate precision and bias goals instead of a combined total error goal. This opinion recommends careful consideration of the differences in the concepts of accuracy and traceability and the appropriateness of different measures, particularly TAE as a measure of accuracy and MU as a measure of traceability. TAE is essential to manage quality within a medical laboratory and MU and trueness are essential to achieve comparability of results across laboratories. With this perspective, laboratory scientists can better understand the many measures and models needed for analytical quality management and assess their usefulness for practical applications in medical laboratories.

Abstract:Assays for total and allergen-specific (s) IgE are essential serological tests in the diagnostic work-up of immediate type hypersensitivity reactions and atopic diseases. Technical performance characteristics and clinical utility of IgE tests have been published in international guidelines. In the USA and in Europe, IgE tests are mainly performed by accredited medical laboratories and in Germany they are also performed by allergists carrying an OIII-limited license. Both have to perform continuously internal and external quality control measures including proficiency trials twice a year (in Germany). Due to the heterogeneity of the assay’s core allergen reagents, complex extracts and more recently defined allergenic molecules, and heterologous assay calibration, the results of qualitative and quantitative sIgE tests from different diagnostic manufacturers can vary considerably. Proficiency trial results are subsequently grouped according to each assay type. Passing acceptance criteria depend on national rules and regarding quality management. Future challenges include a more valid quantification of sIgE which would allow true comparisons with the international units for total IgE, and the use of harmonized allergen reagents for the most important allergen sources, which have hampered inter-assay comparability in the past.
