实验室内部的质量控制方法

Quality Control Methods Within the Laboratory

质量管理是检验检测机构赖以生存的生命线,是检验检测机构工作中的重中之重。质量控制是质量管理的一部分,包括实验室内部质量控制和实验室外部质量控制,实验室内部质量控制的方法有很多,如:标准样品分析、加标回收率分析、平行样分析、密码标样分析、仪器比对、方法比对、留样复测等。质量控制手段可以控制实验室分析人员的分析误差,保证测试结果的精密度和准确度达到规定的质量要求。

Quality management is the lifeline on which inspection and testing institutions rely for survival,and is the top priority in the work of inspection and testing institutions.Quality control is a part of quality management,including internal and external quality control in the laboratory.There are many methods for internal quality control in the laboratory,such as standard sample analysis,spiked recovery analysis,parallel sample analysis,password standard sample analysis,instrument comparison,method comparison,retention sample retesting,etc.Quality control measures can control the analytical errors of laboratory analysts,ensuring that the precision and accuracy of test results meet the specified quality requirements.
