摘要:

目的 进行血红蛋白(Hb)测定参考方法实验研究,为开展Hb测定正确度验证试验提供保障。方法 按照国际血液学标准化委员会(ICSH)要求,在UV-2550分光光度计上使用日本临床化学参考物质标准研究院赋值的有证低、中、高3个浓度水平Hb参考物质和2016年上海市临床实验室第1次室间质评血细胞分析正确度验证的2个调查样品,进行Hb测定总精密度、准确度和传递性等实验研究。结果 5种样品Hb测定参考方法总精密度(CV)<0.5%,3个浓度水平Hb参考物质准确度符合参考物质证书要求,615家临床实验室测定Hb总均值(x?)和不同品牌血液分析仪Hb测定值与参考方法赋值之间偏移<2.7% 。结论 用UV-2550分光光度计进行Hb测定参考方法实验研究的精密度、准确度均符合要求,Hb浓度能很好地传递到厂商常规血液分析仪。

Abstract:

Objective To investigate the reference method for hemoglobin(Hb)determination,and to provide a reference for trueness verification of Hb determination. Methods According to the requirements of the International Council for Standardization in Haematology(ICSH),UV-2550 spectrophotometer was used for Hb reference materials with low,medium and high levels being labeled by Japanese Reference Material Institute for Clinical Chemistry Standards and 2 trueness verification samples in the first External Quality Assessment of Shanghai Clinical Laboratory 2016. The precision,accuracy and comparability were analyzed. Results The total precision(CV)of the 5 samples using the reference method for Hb determination was <0.5%. The accuracy of Hb reference materials with 3 levels met the certification of reference materials. The bias of Hb determination total means (x?) determined by 615 clinical laboratories and Hb determination values by hematological analyzers with different brands was <2.7%,compared to reference method assignments. Conclusions The precision and accuracy of reference method for Hb determination by UV-2550 spectrophotometer meet related requirements. The level of Hb can be delivered well to routine hematological analyzers.

Key words: Reference method for hemoglobin determination, UV-2550 spectrophotometer, Trueness verification
