摘要
目的 通过收集牛奶中金黄色葡萄球菌日常检测过程,以及同步测试质控样品中的金黄色葡萄球菌检测结果,探讨质控图在牛奶中金黄色葡萄球菌定量检测过程中的应用。方法 利用构建单值控制图和移动极差控制图中心线、上警示限、下警示限、上控制限、下控制限对检测数据进行监控,采用标准差和移动极差控制图界限内和界限线外的数据点对实验室检测过程进行监控和评估,判断实验检测过程人员、仪器、试剂的状态。结果 通过观察实验检测数据所在范围,分析数据分布特点和变化,表明单值控制图和移动极差控制图可以有效监控牛奶中金黄色葡萄球菌检测过程,数据结果可靠。结论 该质控图的构建为实验室检测该项目提供了一种有效的食品卫生质量监控手段,有助于促进实验室检测过程的质量控制工作的顺利开展。
Objective The application of quality control chart in the quantitative detection of Staphylococcus aureus in milk was discussed by collecting the routine detection process of Staphylococcus aureus in milk and testing the results of Staphylococcus aureus in quality control samples simultaneously.Methods Monitoring the detection data by utilizing the center line of the single value control chart and the moving range control chart,an upper warning limit,a lower warning limit,an upper control limit and a lower control limit,standard error and data point inside and outside the boundary of the range control chart are used to monitor and evaluate the laboratory detection process,and the status of the personnel,instruments and reagents in the experimental detection process is judged.Results By observing the range of test data and analyzing the distribution characteristics and changes of data,the results showed that single value control chart and moving range control chart could effectively monitor the detection process of Staphylococcus aureus in milk,and the data results were reliable.Conclusion The construction of the quality control chart provides an effective means of food hygiene quality control for laboratory testing of the project,and helps to promote the smooth development of the quality control work in the laboratory testing process.
