摘　　要：临床血沉标准物质可以保证血沉测量结果在时间和空间上的准确性和可比性,从而保证实现有效溯源。本文采用国际血液学标准委员会(ICSH)血沉参考方法对其进行定值,并对血沉标准物质建立了一套合理完整的不确定度评定方案:首先对标准物质不确定度的主要来源进行分析,然后分别对标准物质均匀性、稳定性和定值过程引入的不确定度分量进行计算,最后综合计算出血沉标准物质的不确定度。Clinical reference material of erythrocyte sedimentation rate（ ESR） can ensure the accuracy and comparability of ESR in time and space to realize its effective traceability. Reference method of International Council for Standardization in Haematology（ ICSH） is used to define the ESR value. This paper establishes a complete and rational assessment scheme for uncertainty of ESR reference material. Firstly the main source that affects the uncertainty of reference material is analyzed, then the uncertainty component introduced by stability, homogeneity and value defi-nition process of the reference material is calculated respectively, and finally the uncertainty of reference material is calculated synthetically.
