Review and Analysis of a Case of Total Bacterial Count Measurement Audit
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.
