22.03 EU/mg is at the sensitivity limit of Janoshik's LAL method. The true value is unspecified; treating this as a point estimate is overstating precision.

Section 3
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.
High endotoxin 10.38 EU/mg on high-purity material vs purity suggests water quality at the fill step. If the lot was lyophilised from non-purified water, this is the expected finding.
