Protocols should really take into account the source of endotoxins used in the review, bearing in mind that purified bacterial endotoxins may possibly react in a different way from native resources of endotoxins.
The monocyte activation test (MAT) is yet another proposed strategy to test for endotoxins depending on monocytes in human blood. It measures the release of cytokines from these because of the presence of pyrogens, essentially mirroring the method by which these toxins trigger fever in people (and rabbits, as in the original pyrogen test).
