The rabbit pyrogen test (RPT) stays a feasible mammalian test design when testing for non-endotoxin pyrogens and many different items for which LAL is proscribed. One particular-time pyrogen testing might also be essential by regulatory authorities to aid program utilization of endotoxin tests. All in vivo
