Abstract

Providers of external quality assessment (EQA) programs evaluate data or information obtained and reported by participant laboratories using their routine procedures to examine properties or measurands in samples provided for this purpose. EQA samples must offer participants an equal chance to obtain accurate results, while being designed to provide results in clinically relevant ranges. It is the responsibility of the EQA provider to meet the necessary requirements for homogeneity, stability and some other properties of the EQA items in order to offer participants a fair, reliable and technically interesting EQA experience. Thus, the samples are at the heart and in the centre of EQA and its success depends on their quality. This manuscript describes the requirements for EQA samples and the activities of EQA providers to achieve them.

EQA的幕后——外部质量评估（EQA）的特征、能力、效益和资产。

外部质量评估（EQA）程序的提供者使用其常规程序评估参与者实验室获得和报告的数据或信息，以检查为此目的提供的样品的性质或测量值。EQA样本必须为参与者提供获得准确结果的平等机会，同时设计用于提供临床相关范围的结果。为了给参与者提供公平、可靠和技术上有趣的EQA体验，EQA提供者有责任满足EQA项目的同质性、稳定性和其他一些属性的必要要求。因此，样品是EQA的核心和中心，它的成功取决于它们的质量。本文描述了EQA样品的要求以及EQA供应商为实现这些要求而进行的活动。

期刊介绍： Clinical Chemistry and Laboratory Medicine (CCLM) publishes articles on novel teaching and training methods applicable to laboratory medicine. CCLM welcomes contributions on the progress in fundamental and applied research and cutting-edge clinical laboratory medicine. It is one of the leading journals in the field, with an impact factor over 3. CCLM is issued monthly, and it is published in print and electronically. CCLM is the official journal of the European Federation of Clinical Chemistry and Laboratory Medicine (EFLM) and publishes regularly EFLM recommendations and news. CCLM is the official journal of the National Societies from Austria (ÖGLMKC); Belgium (RBSLM); Germany (DGKL); Hungary (MLDT); Ireland (ACBI); Italy (SIBioC); Portugal (SPML); and Slovenia (SZKK); and it is affiliated to AACB (Australia) and SFBC (France). Topics: - clinical biochemistry - clinical genomics and molecular biology - clinical haematology and coagulation - clinical immunology and autoimmunity - clinical microbiology - drug monitoring and analysis - evaluation of diagnostic biomarkers - disease-oriented topics (cardiovascular disease, cancer diagnostics, diabetes) - new reagents, instrumentation and technologies - new methodologies - reference materials and methods - reference values and decision limits - quality and safety in laboratory medicine - translational laboratory medicine - clinical metrology Follow @cclm_degruyter on Twitter!
