The monocyte activation test (MAT) is an additional proposed process to test for endotoxins determined by monocytes in human blood. It actions the release of cytokines from these mainly because of the existence of pyrogens, essentially mirroring the process by which these toxins induce fever in individuals (and rabbits, as in the first pyrogen test).
Though this direction is not meant to handle Organic assays, lots of the principles while in the steering are relevant to bacterial endotoxins testing. We update assistance documents periodically. To be sure to have The latest Edition of the steering, Test the FDA Medicine steering Website at

This could imply that Preliminary pyrogen (MAT or RPT) testing could possibly be required to display the absence of non-endotoxin pyrogens before relying only on Wager. In exercise this is commonly solved by testing three batches to display that non-endotoxin pyrogens are usually not existing.
Even though endotoxins are regarded as the most vital, this doesn't suggest that each one other pyrogens is usually ignored by default.
