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.
外部质量评估（EQA）计划的提供者会使用参与者实验室的常规程序来评估所获得和报告的数据或信息，以检测为此目的提供的样本中的特性或被测量物。EQA样本必须为参与者提供获得准确结果的平等机会，同时其设计要能在临床相关范围内得出结果。EQA提供者有责任满足EQA项目在均匀性、稳定性和其他一些特性方面的必要要求，以便为参与者提供公平、可靠且在技术上有趣的EQA体验。因此，样本是EQA的核心，其成功取决于样本质量。本手稿描述了EQA样本的要求以及EQA提供者为实现这些要求所开展的活动。
