Endotoxin undetectable means below the detection limit of on Janoshik'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.
6.89 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.
No endotoxin figure on this record, which is true of roughly three quarters of the index. It is the one measurement that cannot be inferred from any other and the one most often omitted.
11.09 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.
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.
