Abstract: Objective The quality of pathological sections of laboratory animals made in the early stage was analyzed to provide reference and guidance for improving the level of section making. Method A total of 1800 slices were randomly selected as the research objects, the failure rate was calculated according to the relevant quality control standards, and the causes of the failure were analyzed. Result The optimal slice rate was 90. 17% (1 623 / 1 800) , and the bad slice rate was 9. 83% ( 177 / 1 800) . The proportion of grade a film is 31. 50%, which should be further improved. The failure rate is within the acceptable range. Conclusion Standardized sampling operation, reasonable selection of fixed solution and fixed time according to the species and age of laboratory animals, strict control of embedding process, improvement of sectioning technology, timely replacement of reagent and other factors can help improve the quality of pathological sections of laboratory animals and facilitate scientific research.
