红细胞沉降率参考方法、魏氏法和仪器法的应用比较

目的探讨红细胞压积(PCV)对红细胞沉降率(ESR)测定的影响及美国临床实验室标准化研究所(CLSI)H2-A4文件参考方法、魏氏法、LDY-CX40型仪器法3种检测ESR方法的可比性。方法按照CLSI参考方法调整1名健康人PCV后检测ESR;随机选择60例门诊和病房患者,分别采用CLSI参考方法、魏氏法与LDY-CX40型仪器法同时测定ESR。结果 PCV对ESR的影响为一倒抛物曲线:Y=611.81X2-698.12X+200.31,决定系数(r2)=0.994 5;不同检测方法间配对t检验显示P<0.01;参考方法、魏氏法、仪器法3者进行两两线性回归分析,r2均>0.976(P<0.01);魏氏法和仪器法的结果均在CLSI制定的比较参考方法和工作方法的可接受范围内。结论 PCV对ESR的影响十分明显,应该将PCV调整在恒定的一个水平,才能获得一个更准确和更有价值的ESR结果;3种不同的检测方法之间差异有统计学意义,应该使用不同的参考区间。

Application comparison of ESR reference method,Westergren method and instrumental method

Objective To study the influence of packed-cell volume(PCV) in red blood cell to erythrocyte sedimentation rate(ESR) and the comparability between ESR reference method Clinical and Laboratory Standards Institute(CLSI),Document: H2-A4],Westergren method and ESR instrumental method(LDY-CX40).Methods The ESR after adjusting PCV of a healthy subject was measured according to CLSI reference method.60 cases of inpatients and outpatients were selected randomly,and their ESR were measured by CLSI reference method,...
