Pooling would frequently be accepted for little-quantity parenterals (These with volumes of 100 mL or much less) assuming that the MVD is altered to the proportional, lower value due to opportunity for diluting a device containing destructive levels of endotoxins with other models containing decreased, much less dangerous, amounts of endotoxins.
