When the host’s immune system is weak, or simply a substantial standard of infection is encountered, the germs could potentially cause sepsis and its involved threats.
Significant deviations involve, but aren't automatically restricted to: bigger endotoxin concentration launch criteria, sampling from much less than a few (three) lots for inhibition/enhancement testing, lesser sensitivity to endotoxins, and a device rinsing protocol resulting in larger dilution of endotoxins than that advised Within this guidance.
