Use Cases

• Pharmaceutical Industry: Pyrogen testing plays a critical role in the pharmaceutical industry. It ensures that injectable drugs and vaccines are safe for human use. These products are administered directly into the bloodstream, making them highly sensitive to contamination. Even a small amount of pyrogen can cause fever, shock, or other immune reactions. By conducting thorough pyrogen testing, manufacturers can detect and eliminate harmful substances before the drugs reach patients. Regulatory authorities like the FDA and WHO mandate such testing to maintain high safety standards. This process helps build trust in pharmaceutical products and reduces the risk of adverse health events.
• Medical Devices: Medical devices that come in contact with blood or cerebrospinal fluid must undergo pyrogen testing. Examples include catheters, surgical implants, and dialysis tubing. These devices can cause serious febrile reactions if contaminated with pyrogens. The safety threshold for endotoxins in these devices is defined based on how and where the device will be used. Pyrogen testing confirms that the endotoxin levels are within safe limits. This is vital for protecting patient health during surgeries or long-term treatments.
