Method Description

The In Vitro Pyrogen Test using Human Whole Blood/IL-6(WBT-IL6) 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 have 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 for the rabbit pyrogen test or the bacterial endotoxin test (Limulus amebocyte lysate assay).
