摘　　要：目的根据医学实验室对测量项目的预期目标,选择对应的目标测量不确定度,促进实验室不断提高测量质量。方法根据米兰模型(Milan models)定义的测量不确定度性能规范,以及室间质量评价方案的分析性能规范,对本实验室测量项目实际应用的目标测量不确定度进行分析,提出医学实验室选择测量目标不确定度的参考原则。结果单一的室间质量评价方案分析性能规范无法满足医学实验室测量预期目标的需求,米兰模型为医学实验室提供了多元化选择模型,适用于不同预期目标的医学实验室测量应用。结论医学实验室可采用多元化性能规范选择适合测量预期目标的目标不确定度,以促进检验质量水平不断提高。目前,并非所有的医学实验室测量项目都有多种性能指标可供选择,空间质量评价方案的分析性能指标仍是目标测量不确定度的选择之一。Objective To select corresponding target measurement uncertainty(TMU)based on the expected goals of measurement items in medical laboratories,aiming to consistently enhance measurement quality.Methods Utilizing the performance specifications of measurement uncertainty as defined by the Milan models and the analytical performance specifications of external quality assurance(EQA)scheme,the study analyzed TMU in the practical application of laboratory measurement items.A guiding principle for selecting TMU in medical laboratories was suggested.Results A singular analytical performance specification from the EQA scheme does not satisfy the requirements of the anticipated goals of medical laboratory measurement.The Milan models offer a diverse selection model for medical laboratory measurements and cater to varying expected goals of such measurements.Conclusion Medical laboratories can use the diverse performance specifications to choose an appropriate target uncertainty that aligns with the expected measurement goals,fostering continuous quality improvement. Currently, not all medical laboratory measurement items offer multiple performance specifications for selection. The analytical performance specification of EQA remains a viable option for TMU.
