Bacterial Endotoxin

Bacterial endotoxin testing is a critical safety requirement for pharmaceutical and biomedical products. Bacterial endotoxins are released from Gram-negative bacteria when the microorganism dies or the cell wall is denatured. Endotoxins are commonly found everywhere in our environment and it is the most significant pyrogen in parenteral drugs and medical devices. These endotoxins can cause fever and septic shock if they enter a patient’s bloodstream. Thus, any products that enter the human body must be tested for the presence of endotoxins prior to market release. MTS offers different bacterial endotoxin methods that utilize limulus amebocyte lysate (LAL). LAL is the most sensitive and specific method available for the detection of endotoxins.
