摘要 目的应用NCCLS EP5-A文件对日立7600全自动生化分析仪的精密度性能进行评价,以确定其是否满足临床的需要。方法在全自动生化分析仪上,根据NCCLS EP5-A文件,用稳定的实验样品分别对采用速率法、终点法和免疫散射比浊法检测的项目进行精密度试验,对其批内标准差(Swr)、批间标准差(Srr)、天间标准差(Sdd)和总不精密度(S1)进行评价。结果检测系统检测常规生化项目的批内标准差小于美国的临床实验室室间质量评估允许误差的1/4,天间标准差小于该允许误差的1/3。说明由实验评估的总不精密度均可接受。结论精密度既是临床检验的方法评价,也是检测系统性能评价的重要指标之一。NCCLS EP5-A精密度性能评价方法能够较为严密地反映出自动生化分析仪的长期使用性能是否能符合日常常规工作的质量要求。
