biocompatibility testing
Testing to ensure medical devices and their sterilization residues are safe for human contact.
Full Definition
Biocompatibility testing evaluates the safety of medical devices and any chemical residues from sterilization processes when they come into contact with human tissues or bodily fluids. This testing is particularly critical for devices that undergo chemical sterilization methods like ethylene oxide, which can leave potentially harmful residues. Testing protocols assess cytotoxicity, sensitization, irritation, and systemic toxicity according to established standards. Results determine safe residue limits and required aeration times for chemically sterilized devices. Biocompatibility testing is essential for regulatory approval and ensuring patient safety throughout the device lifecycle.
Usage
Usage note: Distinguish from microbiological testing; focuses on chemical safety rather than sterility.
