For human and animal prescription drugs, some USP monographs continue to demand a rabbit pyrogen test. In spite of these monographs, a organization might substitute an endotoxins test or substitute cell-based test When the company can demonstrate equal pyrogen detection.
FDA also doesn't advise pooling in-system samples from different in-method levels of your producing course of action as it can be tough to make sure the homogeneity of those products.
Furthermore, Uncooked substance and ultimate item need to also be tested for the presence of bacterial endotoxins. Lonza's big selection of pyrogen and endotoxin testing options supports your attempts in testing, which includes for vaccines, cell and gene therapies and biologics.
