A new quality control model using performance goals based on biological variation in External Quality Assurance Schemes (EQAS) is described. The proposed model aims to use assay (analytical) CV(A), bias and total error available from participation in EQAS to describe assay performance using minimum, desirable and optimum quality specifications based on biological variation. The model provides further analysis of EQAS data and should be useful in better management of laboratory quality control, as it provides further information that can facilitate trouble-shooting. Additionally, it can help in evaluating the performance of current and proposed new laboratory methods by applying a unifying system if different EQAS are used to cover a range of analytes.
本文描述了一种新的质量控制模型，该模型在外部质量保证计划（EQAS）中使用基于生物学变异的性能目标。所提出的模型旨在利用参与EQAS获得的分析（检测）变异系数（CV(A)）、偏差和总误差，根据生物学变异，使用最低、理想和最佳质量规范来描述检测性能。该模型对EQAS数据进行了进一步分析，有助于更好地管理实验室质量控制，因为它提供了有助于故障排查的更多信息。此外，如果使用不同的EQAS来涵盖一系列分析物，通过应用统一系统，该模型有助于评估当前和拟议的新实验室方法的性能。
