The monocyte activation test (MAT) is an additional proposed process to test for endotoxins based upon monocytes in human blood. It actions the discharge of cytokines from these due to existence of pyrogens, generally mirroring the procedure by which these toxins result in fever in humans (and rabbits, as in the first pyrogen test).
