摘要Endotoxins have been credited for over 50％ of sepsis cases,with significantly greater mortality.1A literature indicates wide-spread agreement that early detection of endotoxemia,endotoxin in the bloodstream,is the major key for patient survival from sepsis.2 Today the most popular endotoxin detection system is bacterial endotoxins test (BET),adopted by most pharmacopoeias.Interference test is a part of the bacterial endotoxin inspection method,used to judge whether the sample can be applied in BET.However,Limuloid resources are exhausted in China,which is an important source for LAL.Here,we reported 5 simple models for interfering factors test in the BET,and compared new models with the United States Pharmacopoeia 36 (USP36).
