摘　　要：目的　总结 1 8年来开展 Hb测定室间质评经验 ,寻找提高测定准确性的规律。方法　对 1 8年来Hb室间质评 41 82份回报数据进行统计 ,采用变异系数及偏差指数来衡量判别室间质评总体成绩及单个实验室水平的差异 ;同时对偏差指数和改良偏差指数 ,高、低 Hb含量的室间质评 CV及室间质评中极端值的取舍方法和过失误差发生率进行了分析比较。结果　 1 8年室间质评 CV由 1 983年的 8.1 %减低到2 0 0 0年的 1 .8%,改良偏差指数由 1 995年的 0 .71下降到 2 0 0 0年的 0 .3 6 ,达到了国内领先和国际水平。结论　采用统一分发 Hb质控液和定值 Hb液 ,定期进行室间质量评价 ,是一种提高 Hb测定准确性和减小变异的有效手段 ,在评价方法上 ,以采用 Grubbs氏法取舍极端值及国际通用的偏差指数法 (或改良 DI法 )Objective To review the experience of Interlaboratory Quality Assessment for hemoglobin in 18 years.Methods 4182 data of Interlaboratory Quality Assessment for hemoglobin in 18 years was dealed with statistics.Total achievement and the difference of each laboratory of Interlaboratory Quality Assessment for hemoglobin were evaluated by CV and DI,and furthermore DI & improved DI, CV in varient concentration hemoglobin,accept of abnormal value,ratio of error was analysed.Results CV was reduced from 8.1% in 1983 to 1.8% in 2000.Improved DI was reduced from 0.71 in 1995 to 0.36 in 2000.Conclusions It is effective to improve accuracy and reduce CV with uniform Hb controlls and standard Hb.DI or improved DI is satisfactory.
