摘　　要：目的以丙戊酸为例,评价化学发光微粒子免疫检测法(CMIA)与荧光偏振免疫检测法(FPIA)测定癫痫患者血浆中抗癫痫药物浓度的一致性。方法将同一样本在同一天内分别采用CMIA法和FPIA法测定,测定值用Passing-Bablok回归法、Bland-Altman法及配对t检验进行一致性分析。结果 CMIA法(y)和FPIA法(x)丙戊酸的回归方程为y=1.0049x-0.9851(R2=0.978,n=318),显示2种方法相关性良好;Bland-Altman法结果表明CMIA法和FPIA法对丙戊酸的检测偏倚在在临床允许范围内,具有较好的一致性;配对t检验显示2种方法有差异。结论 CMIA法和FPIA法测定癫痫患者血浆中丙戊酸浓度具有较好的相关性与一致性,2种测定方法可以相互替代。但存在系统误差,在临床治疗中,应注意校正、调整和选择。Objective To evaluate the consistency of chemiluminescence microparticle immunoassay（CMIA） and fluorescence polarization immunoassay assay（FPIA） in determination of antiepileptic plasma drugs concentration with valproic acid as an example. Methods CMIA and FPIA methods were applied to determine the plasma concentration of valproic acid in the same sample, respectively. Then the consistency of the two methods with Passing-Bablokregression and Bland-Altman method was investigated. Results The regression equation of the two determination results by CMIA（y） and FPIA（x） was y =1.0049x-0.9851（R2=0.978,n=318）, which showed the correlation of the two methods was good. Bland-Altman analysis showed that the consistency of the two methods for determining was good. Conclusion CMIA and FPIA methods for determination of valproate plasma concentrations had good correlation, but there was systematic error. In the clinical treatment, we should pay attention to make some adjustment and choice.
