摘 要 目的 建立测定人全血中他克莫司(TAC)浓度的方法,并将其应用于临床。方法 采用甲醇沉淀蛋白的方法处理全血样
品。采用液相色谱-串联质谱(LC-MS/MS)法进行测定,以子囊霉素为内标,使用Kinetex F5 100Å色谱柱,以含0.2 mmol/L甲酸的
0.1 mmol/L醋酸铵溶液和甲醇为流动相进行梯度洗脱,流速为0.4 mL/min,进样体积为5 μL;采用电喷雾离子源在正离子模式下
进行多反应监测(TAC m/z 821.6→768.6,子囊霉素m/z 809.4→756.1)。以2025年9月1-30日于南京医科大学附属儿童医院接受
TAC 治疗的 83 名患儿的 86 例全血样本为研究对象,采用上述方法测定全血中 TAC 浓度,并通过 Spearman 相关性分析、Bland-
Altman分析、Passing-Bablok回归分析评估上述方法与传统酶放大免疫分析(EMIT)法的相关性和一致性。结果 TAC的线性范围
为 0.5~100 ng/mL,准确度、精密度、提取回收率、基质效应、稳定性试验的考察结果均符合相关要求。临床应用结果显示,LC-
MS/MS法和EMIT法测定的患儿全血中TAC浓度的中位值分别为4.4、4.0 ng/mL,且两种方法具有强相关性(相关系数为0.848 1)
与良好的一致性(平均相对偏差为6.5%)。结论 本研究成功建立了测定人全血中TAC浓度的LC-MS/MS法,且该法与EMIT法具
有强相关性和良好的一致性,可用于临床治疗药物监测。

ABSTRACT OBJECTIVE To develop a method for the determination of tacrolimus (TAC) concentration in human whole blood
and to apply it in clinical therapeutic drug monitoring. METHODS Whole blood samples were processed by protein precipitation
with methanol. The determination was performed using liquid chromatography-tandem mass spectrometry (LC-MS/MS), with
ascomycin serving as the internal standard. Chromatographic separation was carried out on a Kinetex F5 100Å column with a
mobile phase consisting of 0.1 mmol/L ammonium acetate containing 0.2 mmol/L formic acid and methanol. Gradient elution was
performed at a flow rate of 0.4 mL/min. The injection volume was 5 μL. Detection was conducted using multiple reaction
monitoring (m/z 821.6→768.6 for TAC; m/z 809.4→756.1 for ascomycin) with an electrospray ionization source in positive ion
mode. The study focused on 86 whole blood samples collected from 83 pediatric patients who received TAC therapy at Children’s
Hospital of Nanjing Medical University from September 1 to 30, 2025. The aforementioned method was employed to measure the
TAC concentration in the whole blood samples. The correlation and agreement between the aforementioned method and the
traditional enzyme multiplied immunoassay technique (EMIT) were evaluated through Spearman correlation analysis, Bland-Altman
analysis, and Passing-Bablok regression analysis. RESULTS The linear range of TAC was 0.5-100 ng/mL; the evaluation results
for accuracy, precision, extraction recovery, matrix effect,
