Summary
Bacterial endotoxins are among the most common pyrogenic contaminants found on healthcare products and medical devices. Their presence can trigger serious patient reactions if not adequately controlled, making endotoxin monitoring an essential component of many quality and microbiological control programs.
In this TechTalk webinar, we introduce key microbiological concepts, including the relationship between pyrogens and bacterial endotoxins, before exploring the historical development of endotoxin testing and the role of the horseshoe crab in the widely used LAL testing methodology.
We discuss the principles of bacterial endotoxin testing, regulatory expectations, and practical considerations for method selection. The session also explains how ISO 11737-3 provides guidance for the validation and routine use of endotoxin testing methods to support compliance and patient safety objectives.
