Endotoxin undetectable means below the detection limit of on VendorInvestigate'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
Records submitted
A submitter chose to buy this material and to pay for this assay. That choice is the selection mechanism behind the whole index and it is not random.
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.
7.53 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.
