摘要:

目的 基于同位素稀释液相色谱-串联质谱(ID-LC-MS/MS)技术建立检测血清伏立康唑的候选参考方法。方法 以甲醇为沉淀剂,采用蛋白沉淀法(PPT)对样本进行前处理。以伏立康唑-2H3为内标,建立基于ID-LC-MS/MS的血清伏立康唑候选参考方法。评估所建立方法的线性、定量限(LOQ)、检测限(LOD)、准确度、精密度、基质效应、稳定性。结果 ID-LC-MS/MS测定血清伏立康唑的线性范围为0.2~16.0 μg·mL-1,定量限为0.08 μg·mL-1,检测限为0.016 μg·mL-1。加标回收率为97.26%~98.48%。批内变异系数(CV)<1%,批间CV<2%。相对基质效应为-1.87%~0.33%。样本分别经室温[(23±2)℃]放置4、8 h和-20 ℃反复冻融5次,经前处理后的样本在室温和自动进样器(8 ℃)分别放置4、8、12、24 h,回收率为95.63%~99.50%,检测结果稳定。相对扩展不确定度≤3.34%。结论 建立了基于ID-LC-MS/MS的血清伏立康唑候选参考方法,可用于该项目的检测标准化。

Abstract:

Objective To establish a candidate reference measurement method for serum voriconazole by isotope dilution liquid chromatography-tandem mass spectrometry (ID-LC-MS/MS). Methods The samples were pretreated by protein precipitation (PPT) with methanol as precipitator. Using voriconazole -2H3 as internal standard,an ID-LC-MS/MS for the determination of voriconazole in serum was established. The linearity,limit of quantification (LOQ),limit of determination (LOD),accuracy,precision,matrix effect and stability were evaluated. Results The linear range of serum voriconazole was 0.2-16.0 μg·mL-1,the limit of quantification was 0.08 μg·mL-1,and the limit of determination was 0.016 μg·mL-1. The recoveries were 97.26%-98.48%. The within-run coefficient of variation (CV) was <1%,and the between-run CV was < 2%. The relative matrix effect ranged from -1.87% to 0.33%. The samples were placed at room temperature [(23±2) ℃] for 4,8 h and repeatedly frozen and thawed for 5 times at -20 ℃,and the samples after pre-treatment were placed at room temperature and automatic injector (8 ℃) for 4,8,12 and 24 h,respectively. The recoveries were 95.63% - 99.50%,and the determination results were stable. The relative extended uncertainty was ≤3.34%. Conclusions A candidate reference method for the determination of serum voriconazole based on ID-LC-MS/MS has been established,which can be used for standardization.
