The term "Westergren sedimentation rate" implies that a standardized test is being performed. Questionnaires sent to 177 rheumatologists and 150 clinical laboratory directors showed that a variety of techniques are used to perform the sedimentation rate by the "Westergren" method. A comparative study revealed that the most reproducible results could be obtained with the classical Westergren technique or with a modified Westergren technique using EDTA anticoagulated blood and saline diluent. The use of undiluted whole blood in a Westergren tube was less reproducible and compared poorly with the classical Westergren technique. The results confirm that the undiluted Westergren technique should not be used and that in clinical studies the technique employed for determining the sedimentation rate should be specified.
术语“魏氏血沉率”意味着正在进行一项标准化测试。向177名风湿病学家和150名临床实验室主任发送的调查问卷显示，采用“魏氏”法测定血沉率时会使用多种技术。一项对比研究表明，使用经典魏氏技术或使用乙二胺四乙酸（EDTA）抗凝血液和生理盐水稀释剂的改良魏氏技术能够获得最可重复的结果。在魏氏管中使用未稀释的全血时，可重复性较差，与经典魏氏技术相比效果不佳。结果证实不应使用未稀释的魏氏技术，并且在临床研究中应明确说明用于测定血沉率的技术。
