目的 评价国产乳胶增强免疫比浊法降钙素原(PCT)诊断试剂在西门子ADVIA 2400系统上应用的性能.方法 参考美国临床实验室标准化委员会(CLSI)指南对乳胶增强免疫比浊法PCT诊断试剂在西门子ADVIA 2400系统检测的精密度、准确度及线性范围进行性能验证,同时与参考方法(电化学发光法)进行一致性比较.结果 乳胶增强免疫比浊法在西门子ADVIA 2400系统上测定PCT低值和高值质控品的批内精密度分别为5.5％ 、2.3％,批间精密度分别为6.6％ 、3.1％,总精密度分别为6.6％ 、3.9％.PCT浓度在0.19～49 ng/mL范围的线性良好(r=0.9957).乳胶增强比浊法与电化学发光法的Passing-Bablok回归方程为Y=0.846 X+0.0772(...

Objective To evaluate the performance of domestic latex-enhanced immunoturbidimetric procalcitonin(PCT)diagnostic reagent on ADVIA2400system.Methods The precision,accuracy and linear range of latex-enhanced immunoturbidimetric PCT diagnostic reagent was tested by ADVIA2400system in reference to CLSI guide.At the same time,the consistency of this method was compared with the reference method,which was electrochemistry luminescent method.Results On Siemens ADVIA2400system,through latex-enhanced immunoturbidimetric method,the tested intra-assay pr...
