Sizeable deviations include, but are certainly not necessarily limited to: bigger endotoxin focus launch standards, sampling from fewer than 3 (3) a lot for inhibition/enhancement testing, lesser sensitivity to endotoxins, and a device rinsing protocol resulting in higher dilution of endotoxins than that advisable With this steerage.
The age, gender and housing circumstances click here with the rabbit could also have an effect on the outcome on the rabbit test end result. An alternative to the rabbit test (
The endotoxins limit may be modified appropriately. In almost any case, the rinse/extract process shouldn't end in a increased dilution of endotoxin than advisable in USP . For inhibition/improvement testing, the two the rinse/extract Alternative and the device eluate/extract must be tested.
