摘要
目的比较反相高效液相色谱(RP-HPLC)法与荧光偏振免疫(FPIA)法测定血浆卡马西平浓度的差异性和相关性。方法收集卡马西平血浆样本50例,分别采用RP-HPLC和FPIA进行测定,采用配对t检验比较两者均数的差异;Bland-Altman进行一致性分析;Deming回归法进行相关性分析。结果 FPIA法的测定结果高于RP-HPLC法,两种测定方法均数之间差异有统计学意义(P<0.05),一致性较差;Deming回归分析显示两种方法之间存在良好的相关性,回归方程为:CFPIA=1.195 3CRP-HPLC-0.144 0,Pearson相关系数为0.968 5。结论在制定卡马西平个体化给药方案时应充分考虑不同检测方法的影响,正确解读检测结果,提高个体化用药水平。
Objective To evaluate the correlation and difference of reversed phase high performance liquid chromatography （ RP-HPLC ） and fluorescence polarization immunoassay （ FPIA） on determining serum concentration of carbamazepine. Methods Fifty serum samples were collected, both RP-HPLC and FPIA methods were employed to determine the concentration of carbamazepine.The results were analyzed by paired t test, Bland-Altman and Deming regression methods, respectively. Results The results of measuring 50 samples by the two methods showed that FPIA datas were significantly higher than RP-HPLC datas,and there was statistically significant difference（ P 〈0. 05 ） and poorer consistency between two methods; There was good correlation between carbamazepine concentrations determined by the two methods. Deming regression equation was CmA = 1.195 3 CRP-HPLC-0.144 0, and Pearson correlation coefficient was 0.968 5. Conclusion Clinicians should pay more attention to the difference of carbamazepine concentration determination by different methods when carbamazepine individualized dosage regimen was adjusted according to therapeutic drug monitoring.
