Significant deviations involve, but are not automatically limited to: larger endotoxin focus launch criteria, sampling from fewer than a few (three) heaps for inhibition/enhancement testing, lesser sensitivity to endotoxins, and a tool rinsing protocol causing increased dilution of endotoxins than that suggested On this advice.
Endotoxins are responsible for close to 60% of all pyrogen contaminations, while NEPs share is about forty%. Acknowledging this is significant as some pyrogen tests can only realize endotoxins leaving every one of the non-endotoxins undetected.
