Pyrogenicity Testing
Pyrogenicity refers to the ability of substances to induce febrile (fever) responses when introduced into the human body, primarily caused by endotoxins from gram-negative bacteria or other pyrogenic compounds. For medical devices, pyrogenicity testing is essential to evaluate potential fever-inducing contaminants that may originate from manufacturing processes, packaging materials, or device components themselves. Regulatory agencies worldwide, including the U.S. FDA (ISO 10993-11) and European Union Medical Device Regulation (MDR), require pyrogenicity assessment as part of the biological evaluation for most implantable and blood-contacting devices. Meditronics's comprehensive pyrogenicity testing services help medical device manufacturers identify and mitigate pyrogenic risks, ensuring patient safety while meeting stringent global regulatory requirements.
Our Service
Meditronics (a brand of STEMart) provides pyrogenicity testing services which strictly adhere to international standards including ISO 10993-11 and relevant pharmacopeial methods (USP <151>, EP 2.6.8, JP 4.01). We employ a comprehensive range of validated testing approaches:
In Vivo Rabbit Pyrogen Test (RPT)
Gold standard method measuring temperature elevation in rabbits;
Detects both endotoxin and non-endotoxin pyrogens;
Particularly valuable for devices with complex material compositions.
Bacterial Endotoxin Test (BET/LAL)
Quantifies endotoxin levels using Limulus Amebocyte Lysate;
Available as gel-clot, chromogenic, or turbidimetric formats;
Cost-effective with rapid turnaround for routine monitoring.
Monocyte Activation Test (MAT)
In vitro alternative using human blood-derived monocytes;
Detects endotoxin and non-endotoxin pyrogens;
Eliminates animal use while improving human relevance.
Whole Blood Pyrogen Test (WBPT)
Utilizes fresh human whole blood to measure IL-1β release;
Detects broad spectrum of pyrogenic contaminants;
Suitable for devices with complex material interactions;
Provides enhanced sensitivity compared to traditional methods.
Recombinant Factor C (rFC) Assay
Animal-free endotoxin detection using recombinant technology;
Avoids limitations associated with horseshoe crab sourcing;
Sustainable alternative with equivalent sensitivity to LAL.
Our testing protocols incorporate appropriate extraction conditions based on device materials and intended use, following ISO 10993-12 guidance. We customize sample preparation methods to simulate clinical exposure scenarios, including exhaustive, partial, and exaggerated extraction techniques as needed.
