国际血液学标准化委员会（ICSH）关于红细胞沉降率测定改良方法与替代方法的建议。红细胞沉降率（ESR）测定的金标准是 Westergren（魏氏）法。其他 ESR 测定方法也已问世，从对 Westergren 法的适度改良到完全不同的方法学不等。ICSH 成立了工作组以研究这些新途径，并编制关于确认与验证的建议。
ICSH recommendations for modified and alternate methods measuring the erythrocyte sedimentation rate. The gold standard for the determination of the erythrocyte sedimentation rate (ESR) is the Westergren method. Other methods to measure the ESR have become available. They range from modest modifications of the Westergren method to very different methodologies. The ICSH established a Working Group to investigate these new approaches and compile recommendations for validation and verification.
