Precil XC-40型全自动动态血沉测试仪的应用评价

目的比较Precil XC-40型全自动动态血沉测试仪测定结果与传统魏氏法测定结果的相关性和线性。方法分别用自动血沉仪法和传统魏氏法测定238例临床患者1h红细胞沉降率(ESR)。结果经统计学处理,238例ESR在两种方法的测定结果经检验,差异无统计学意义(P>0.05)。在正常参考值范围内,二者测定结果一致。但当ESR>15mm/h后,Precil XC-40型全自动动态血沉测试仪测定中位数高于魏氏法,而且随着测定值增加,二者之间差异越明显。结论全自动动态血沉测试仪对正常标本测定结果与魏氏法接近,而在贫血、脂血标本以及ESR明显升高的标本则应以魏氏法为金标准。

Evaluation of Precil XC-40 automatic dynamic sedimentation analyzer

Objective To understand the correlation and linear between the detection results of Precil XC-40 automatic dynamic sedimentation analyzer and traditional Westergren method. Methods 238 cases of lh erythrocyte sedimentation rate （ESR） were detected by Precil XC-40 automatic monitor analyzer and traditional Westergren method. Results In normal reference range, there was no significant difference of the detection results of ESR be- tween the two methods （P〉0.05）. But when ESR larger than 15 ram/h, the median of XC-40 method was higher than that of Westergren method, and with the increasing of detected value, the differences became more and more obvious. Conclusion Automatic dynamic ESR test method might be identical with Westergren method for the detec- tion of samples in normal reference range, but for the detection of anemia and lipid turbidity samples and samples with increased ESR level, Westergren method should be taken as gold-standard.
