目的探讨3种不同型号全自动生化仪测定血糖结果的可比性。方法按照NCCLS EP9-A2文件的要求，以贝克曼AU5800生化仪为实验仪器(X)，日立7600生化分析仪和强生FS5.1干化学分析仪为比对仪器(Y1和Y2)，收集本院住院和门诊就诊患者高、中、低浓度血清分别在三台生化仪上测定，对测定结果进行比对分析及统计学处理。结果三种不同型号生化仪间检测结果差异无统计学意义(>0.05)，检测结果明显相关(r2>0.95)，血糖测定结果的相关系数为0.9986（X与Y1）和0.9983（X与Y2），三台生化仪在血糖三个医学决定水平测定结果的相对偏差均在可接受范围内。结论血糖在三台生化仪检测的结果具有较好的可比性。“,”Objective To discuss the comparability of serum glucose results detected by 3 dif erent biochemical analyzers. Methods According to NCCLS document EP9-A2, Beckman AU5800 biochemical analyzer is laboratory equipment (X), Hitachi 7600 biochemical analyzer and Johnson FS5.1 dry chemistry analyzer are comparative equipment (Y1and Y2). Col ecting high, medium and low value serum of inpatient and outpatient measured on 3 biochemical analyzers. Results Comparative analysis and statistical analysis. Results The variance analysis showed the results between the 3 biochemical analyzers had no significant dif erence ( >0.05) and were significantly cor elated (r2>0.95), the cor elation coef icients of serum glucose were 0.9986 (X and Y1) and 0.9983(X and Y2). The results showed good comparability. The relative deviation of dif erent levels of medical decision results between the 3 instruments are within the al owable er or range. Conclusion There is good comparability between the results of serum glucose detected by 3 dif erent biochemical analyzers in our hospital.
