为了解日立 7170A型全自动生化分析仪的主要性能 ,对该仪器作出评价 ,使用正常人、病人血清和德国宝灵曼质控品 ,对 8个代表参数作了评价。结果表明 ,各代表项目的变异系数较小 ,仪器的重复性较好 ,经时变化和日间变化小。仪器的携带污染率很低 ,线性范围也较宽 ,准确度高。与OLYMPUS -10 0 0全自动生化分析仪对比 ,各代表项目的相关系数在 0 .991～ 0 .999之间。鉴于该仪器的各项主要指标评价结果均符合设计性能 ,认为日立 7170A型全自动生化分析仪值得推广应用
To understand the main performance of the Hitachi Model 7170A Automatic Biochemical Analyzer, the instrument was evaluated and eight representative parameters were evaluated using normal people, patient serum, and German Bowringmann quality control products. The results show that the coefficient of variation of each representative project is small, the repeatability of the instrument is good, and the change over time and the change between days are small. The instrument carries a low pollution rate, a wide linear range, and high accuracy. Compared with OLYMPUS -100 automatic biochemical analyzer, the correlation coefficient of each representative project is between 0.991 and 0.9999. In view of the evaluation results of the instrument’s main indicators are in line with the design performance, it is considered that the Hitachi 7170A automatic biochemical analyzer is worth popularizing and applying.
