摘要
目的:借助测量审核提高本实验室检测水平和核心竞争力.方法:以中国检验检疫科学研究院测试评价中心提供的作业指导书为依据,采用平板计数法和测试片法分别对样品进行检测.结果:配对t检验显示两种方法的检测结果不具有显著性差异(P＞0.05),两种方法的|Z|值均小于2,为满意结果.结论:平板计数法和测试片法均可用于菌落总数的检测,检测机构可以依据自身条件选择合适的方法来检测样品中的菌落总数.
Abstract
Objective:To improve the testing level and core competitiveness of this laboratory with the help of measurement audit.Method:Based on the operation instructions provided by the Testing and Evaluation Center of the Chinese Academy of Inspection and Quarantine,the samples were tested using the plate counting method and the test piece method.Result:The paired t test showed that there was no significant difference in the detection results of the two methods(P>0.05).The|Z|values of the two methods were both less than 2,which was a satisfactory result.Conclusion:Both the plate counting method and the test piece method can be used to detect the total number of bacterial colonies.Testing institutions can choose the appropriate method to detect the total number of bacterial colonies in the sample based on their own conditions.
