摘要:目的 通过溯源至国际临床化学和检验医学联合会(IFCC )糖化血红蛋白(HbA 1c )一级参考方法,为上海市临床检验中心建立二级参考方法,完善HbA 1c 量值溯源体系。方法 分别采用HA-8180糖化血红蛋白分析仪(简称HA-8180)、Hb-9210糖化血红蛋白分析仪(简称Hb-9210)、Capillarys 2 Flex Piercing 毛细管电泳仪(简称Cap2)、MQ2000-PT 糖化血红蛋白分析仪(简称MQ2000-PT )及各自的配套试剂组成的4种检测系统检测IFCC HbA 1c 工作组提供的24份样本,将检测结果与IFCC 公布的靶值比较,并根据IFCC 的评价规则评价4种检测系统的性能。结果 HA-8180、Hb-9210、Cap2和MQ-2000PT 的变异系数(CV )分别为1.1%、2.0%、2.2%、2.0%,不精密度分别为0.6、1.0、1.1、1.0 mmol/mol ;根据回归方程得出的结果与50 mmol/mol 水平的|偏移|分别为1.0、1.1、0.4、1.0 mmol/mol ;全年整体总误差(TE )分别为 2.2、3.1、2.6、3.2 mmol/mol 。HA-8180的评价结果为“Sliver ”,Hb-9210、Cap2和MQ-2000PT 的评价结果均为“Bronze ”。结论 HA-8180、Hb-9210、Cap2和MQ-2000PT 4种检测系统均符合HbA 1c IFCC 二级参考方法的认证要求。

Abstract :Objective To improve the traceability of glycated hemoglobin A 1c (HbA 1c ) in Shanghai Center for Clinical Laboratory with establishing the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC ) Secondary Reference Measurement Procedure ,through tracing from the IFCC Primary Reference System. Methods Using 4 HbA 1c determination systems ,including HA-8180,Hb-9210,Capillarys 2 Flex Piercing (Cap2) and MQ2000-PT with their original reagents and calibrators ,the results of 24 samples sent by IFCC were compared with the target values assigned by the IFCC Primary Reference System. The performance of the 4 determination systems were evaluated by the IFCC rules. Results The coefficients of variation (CV ) of the 4 determination systems were 1.1% for HA-8180,2.0% for Hb-9210,2.2% for Cap2 and 2.0% for MQ2000-PT. The imprecisions were 0.6,1.0,1.1 and 1.0 mmol/mol ,respectively. The |biases| at the level of 50 mmol/mol were 1.0,1.1,0.4 and 1.0 mmol/mol ,respectively. The total errors (TE ) of whole year were 2.2,3.1,2.6 and 3.2 mmol/mol ,respectively. According to the rules ,HA-8180 got a "Sliver " score ,and Hb-9210,Cap2 and MQ2000-PT got "Bronze " score. Conclusions The 4 determination systems demonstrate traceability to the IFCC Secondary Reference Measurement Procedure.
