Compared with developed countries, the use of laboratory animals for scientific research in China is relatively recent. In the past 40 years, a standardized system of the use of laboratory animals has been constantly improved, which has improved the quality of biomedical research. However, some problems in the writing of standardized documents still persist. To improve the standardization of laboratory animal protocols and to promote better adherence to such standards, we summarize and analyze common problems in standardized documents for the use of laboratory animals. We provide correct examples using the basic framework of standard documents and according to the requirements of GB/ T 1.1 -2020
