Comparison on two methods of HPLC-MS/MS and MEIA in monitoring the tacrolimus concentrations for organ transplantation patients / 中国临床药理学与治疗学

ABSTRACT

AIM: To compare two methods of HPLC-MS/MS and MEIA to monitor the tacrolimus concentrations for organ transplantation patient.METHODS: After developing and validating the HPLC-MS/MS method to determine the concentrations of tacrolimus,the tacrolimus samples were quantitated by two methods of HPLC-MS/MS and MEIA,respectively.Evaluate two methods by statistical analysis of quantitative results.RESULTS: The mean concentration were(4.86?0.46) ng/mL by HPLC-MS/MS and(5.52?0.43) ng/mL by MEIA.The coefficient correlation of two methods was 0.8771,and the two methods have good correlations in statistics.The mean concentration ratio was(90.3?5.3)%.CONCLUSION: The HPLC-MS/MS method is a more precise method for to determining the effective concentration of tacrolimus,which is suitable for daily TDM.
