Endotoxin undetectable means below the detection limit of on Nordanalyt's system. That does not mean zero and may not reflect actual endotoxin. The cutoff is useful for screening; the absence of a number is not a guarantee.

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.
Endotoxin determined but the LAL method is not stated. Kinetic chromogenic and gel-clot give different results and different sensitivity. The value cannot be interpreted without knowing which.
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.
