Why a dead-clean sterile filter can pass pyrogen straight through

Do you need the top of the ladder?
The dose-response curve in this class flattens near its top. That has direct consequences for whether the final rung is worth climbing.

The masking phenomenon known as low endotoxin recovery means a formulation can return a clean result while containing endotoxin the assay cannot see.
How a claim degrades between the bench and the listing
A badge asserts that something was tested. It does not assert what, when, on whose sample, by what method, or whether the lot on sale is the lot that was tested.
