摘要 目的:对DS5低压阳离子交换色谱法联合梯度规避法和DCA2000免疫法两种糖化血红蛋白分析仪的不同分析方法进行方法学评价。方法:用低压阳离子交换色谱法联合梯度规避法(X)和免疫法(Y)测定糖化血红蛋白,进行回收率、精密度、干扰因素、相关性及参考范围的分析。结果:两种方法的平均回收率均在95%~104%以内,批内、批间的平均变异系数(CV)均〈5%;10.2mmol/L三酰甘油、8.0mmol/L胆固醇、10.1%HbF对两种仪器均无干扰,684umol/L总胆红素对DS5的层析柱有破坏作用,对DCA2000无干扰;两者结果密切相关,相关系数r=0.9957(P〈0.01),n=50,直线回归方程Y=1.09X+0.1%;DS5测定糖化血红蛋白结果较DCA2000偏低;DS5和DCA2000两者参考范围分别为4.0%-6.0%和4.3%-6.5%。结论:DCA2000测定结果比DS5偏高。
