Abstract: Commonly used test quality control methods use comparison, efficacy function diagrams and other ways to analyze the factors affecting the quality of the test, through the direct interference of the influencing factors to achieve quality control. This control method is not only inefficient, but also easy to ignore the error of the analysis process, resulting in poor quality control, low implementation rate and efficiency. In response to the above problems, we study the quality control method of pathogenic microbiological testing based on consistency calibration. Based on the analysis of factors affecting the quality of pathogenic microbiological testing, the test data of pathogenic microbiological testing methods are pre-processed to remove the more obvious error data in the test data. Through a combination of normal calibration and consistency calibration, the test data with higher test accuracy is used as a reference to achieve quality control of pathogenic microbiological tests. The case validation study shows that the method has strong control stability, and the method can improve the test accuracy by about 3.7%.
