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.
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.
