两台日立生化分析仪测定结果可比性研究

目的对同一生化实验室两台日立生化分析仪进行方法学对比及偏差评估，探讨不同仪器间测定结果是否具有可比性。方法以可溯源的日立7180生化分析仪，上海复星长征医学科学有限公司生产的试剂、校准品和质控品组成的检测系统作为目标检测系统（X），7170S为待评系统（Y），在8个工作日内分别测定正常、病理水平质控物各8次和新鲜血清样本40份。计算目标检测系统与待评系统的相对偏差（SE％），以美国临床实验室修正法规规定的室间质量评价允许误差范围的1／2为标准，判断不同检测系统之间的可比性。结果两检测系统测定结果之间的系统误差或均值处的SE％均在临床可接受范围内。结论两检测系统各测定结果具有可比性，可满足临床需要。

The comparative study on the testing results between two Hitachi routine biochemical analyzers

Objective To perform methodical comparison and bias estimation on two Hitachi routine biochemical analyzers in the same laboratory,and explore the comparability of testing results obtained from different equipments.MethodsThe detection system was adopted as the target system(X)which was composed of Hitachi 7180 biochemical analyzer,reagents,calibration preparation and quality control sample produced by Shanghai Fuxing Changzheng Medical Science Co.,Ltd.Meanwhile,Hitachi 7170S was used as evaluated system(Y)...
