参照CLSI EP方案评价直接胆红素试剂分析性能 (摘要)目的通过应用CLSI EP方案分别对国产和进口直接胆红素(DBil)试剂分析性能 进行评价，了解国产直接胆红素试剂分析性能能否满足临床需要。方法在同一台全H动生 化分析仪上，同吋测定试剂准确度、精密度、最低检测限、线性范围、干扰试验、方法比对 实验、稳定性观察等7项技术指标。结果两种试剂准确度测定，其相对偏差±10%；批间 变异系数小于4. 0%；国产DBil试剂线性范围0. 2-595. OWnol/L,进口试剂线性范围 -0. 4-595. 7Mmol/L；国产DBil试剂的最低检测限为0. 4Mmol/L,进口试剂的最低检测限为 0. 9Mmol/L；方法比对实验结果 Y=0? 997X+5. 2467, R2=0. 9996(浓度范围 0. 2-595. OMmol/L)； 抗干扰能力无明显旁异；试剂稳定性相近。结论：国产直接胆红素试剂与进口试剂的分析性 能无显著性差界，能满足临床实验室的需耍。 (关键词)CLSI EP方案；锐酸盐氧化法；直接皿红素；分析性能评价 Evaluation of the analytical performance of Direct Bilirubin (DBil) reagents with CLSI EP document Xie Wen Hui.( Pi ng Cha ng District Chinese Medicine Hospital, Ba Zhong 636400,China) 【Abstract] Objective Through evaluate the analytical performance of domestic Direct Bilirubin (DBil) reagents and imported WAKO Direct Bilirubin (DBil) reagents with CLSI document, understanding performance differences of domestic and imported WAKO Direct Bilirubin. Methods On the same automatic biochemical analyzer, determinate the reagents analytical performance at the same time, such as accuracy, precision, minimum detection limit, linear range^ anti-interference ability, stability, method comparison. Results Determinate accurate of the two reagents, the relative deviation 土 10%; the within run coefficient of variation 4.0%; The linear range of self-made DBil reagent is 0.2-595.Ogmol/L, and the linear range of imported reagent is-0.4-595.7|imol/L) ; The minimum detection limit of domestic DBil reagents was 0.4|imol/L, of the import reagents was 0.9pmol/L; the result of the method comparation was Y=0.997X+5.2467. R2 = 0.9996; there was no significant difference with anti-intcrfcrcncc ability; the two reagents had similar stability. Conclusions There was no significant difference of analytical performance with sei匸made Direct Bilirubin (DBil) reagents and imported WAKO Direct Bilirubin (DBil) reagents. 【key words] CLSI document； Vanadate Oxidizing Method ; Direct Bilirubin (DBil); perfonnance evaluation 胆红索?是红细胞止常或非正常降
