Analysis of census results of 1458 cases of rural women breast disease Bacterial endotoxin interference test: The results showed that the Et value in the range of 0.5 to 2, and Es values between 0.5Et to 2Et, therefore it can be determined that the injection of Latamoxef sodium does not interfere with the bacterial endotoxin test. It is approved that for the test product, each 1mg contains a bacterial endotoxin level of less than 0.3 EU. The LAL method for the detection of bacterial endotoxins has the advantages of simple operation, high sensitivity, good reproducibility, and practicality, making it a simple, rapid, and feasible method. With a sensitivity of 0.5 EU/ml, the LAL method for the bacterial endotoxin test of Latamoxef sodium injection is feasible.
