Method Description

The In Vitro Pyrogen Test using Human Whole Blood/IL-1 Beta (WBT-IL1) is a monocyte activation test (MAT) applied to detect or quantify substances that activate human monocytes or monocytic cells to release pro-inflammatory cytokines, for example tumour necrosis factor alpha (TNFα), interleukin-1 beta (IL-1β) and interleukin-6 (IL-6). These cytokines play a role in fever pathogenesis. Consequently, the MAT can detect the presence of pyrogens in the test sample. The MAT is suitable, after a product-specific validation, as a replacement of the rabbit pyrogen test or the bacterial endotoxin test (Limulus amebocyte lysate assay).

Mar 2009	Adopted/published	The European Pharmacopoeia General Method 2.6.30 Monocyte-activation test was adopted by the European Pharmacopoeia Commission in March 2009 and came into force in September 2009. The In Vitro Pyrogen Test using Human Whole Blood/IL-1 Beta is covered by this text. The MAT is suitable, after product-specific validation, as a replacement for the rabbit pyrogen test or the bacterial endotoxin test.
