Endotoxin tested twice on this lot with varying EU/mg spread. Endotoxin variability in retained samples is larger than most labs acknowledge and the single measurement here is not definitive.

Section 2
Annotations
Signed technical comments on records. The index does not moderate annotations for agreement with its own arithmetic, and several of these disagree with it.
7.53 EU/mg but the material was passed through a sterile sterile filter. Some filters leach endotoxins; the measurement does not distinguish material from filter contribution.
7.77 EU/mg from an older lot. Endotoxins are heat-stable and drift is rare. If this matches fresh-lot median from the same supplier, the number is stable.
