酶放大免疫分析法与二维液相色谱法监测癫痫患者血清中卡马西平浓度的比较
柳航 王敏 金路 张晋萍[摘要] 目的 比較酶放大免疫分析法(EMIT)与二维液相色谱法(2D-HPLC)测定卡马西平血药浓度的差异。 方法 采集67例癫痫患者卡马西平血清样本,分别采用EMIT法和2D-HPLC法测定,其中二维液相的色谱条件如下:第一维色谱柱为ASTON-FAQ C8柱(4.0 mm×100.0 mm,3 μm,ANAX),流动相为乙腈-水(55∶45,v/v),流速为1 mL/min;中间柱为ASTON C18(4.6 mm×10.0 mm,3 μm,ANAX);第二维色谱柱为Diamonsil-C18柱(4.6 mm×200.0 mm,5 μm,Dikma),流动相为乙腈-20 mmol/L乙酸铵(20∶80,v/v,pH=7.0),流速为1.2 mL/min。柱温为40℃,检测波长为285 nm。结果 两种方法差异无统计学意义,且相关性好,回归方程为y(2D-HPLC)=0.9876×x(EMIT)-0.0313,Bland-Altman分析显示两种方法一致性良好。 结论 EMIT法与2D-HPLC法测定的结果具有良好的一致性和相关性,应综合考虑实验室条件和人员配置等方面,采用合适的测定方法。
