ESR-2040动态血沉分析仪检测红细胞沉降率的评价

目的：评价ESR-2040动态血沉分析仪检测红细胞沉降率（ESR）的重复性、准确性。方法随机抽取160例住院患者静脉血样本，每个样本均采用ESR-2040动态血沉分析仪及魏氏法同时测定ESR，同时抽取ESR测定值从低到高的标本5例，采用ESR-2040动态血沉分析仪重复测定10次，并对测定的结果进行统计分析。结果 ESR-2040动态血沉分析仪检测红细胞沉降率具有较好的重复性（CV〈5%），与魏氏法具有良好的相关性。两种方法的测定结果在正常值范围内结果基本一致；血沉结果大于20 mm/h时，魏氏法测定的结果高于仪器法，并且随着测定值的升高二者之间的差异越显著。结论自动血沉仪与魏氏法血沉测定结果在20 mm/h以内时有良好的相关性和准确性，＞20 mm/h时应用魏氏法复检以提高检测值的准确性。

Evaluation of ESR-2040 automated Analyzer in detecting erythrocyte sedimentation rate

Objective To evaluate the repeatability and accuracy of 2040 Automated Erythrocyte Sedimentation Rate （ESR） Analyzer. Methods Using ERS-2040 Automated ESR Analyzer and traditiona1 Weishi method to measure 160 random venous blood samples from hospitalized patient respectively, and extract five samples that the lower to higher from the results of ESR were repeated measurement （n=10） with ERS-2040 Automated ESR Analyzer. The results of ESR were statistically analyzed. Results In detecting ESR, it showed that the ESR-2040 analyzer had a good repeatability （CV〈5%）, The method of ESR-2040 analyzer, compared with traditional Weishi method, showed a satisfactory correlation. At the normal range of ESR, there were no significant difference between the results of ESR from two methods. However, when the results were beyond the range of 20 mm/h,the results from Weishi method were higher than those from analyzer, and the higher the results, the more significant the difference. Conclusion At ESR within 20 mm/h, there were significant correlation and accuracy between ESR-2040 analyzer with traditional Weishi method. At ESR above 20 mm/h, we need to use the traditional Weishi method detecting recheck to improve accuracy of results.
