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.

AX-2025-018595
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.
AX-2025-018862
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.
AX-2024-004502
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.
