Material change biocompatibility | Materials Metric

Material change biocompatibility assessment is required whenever a medical device undergoes a change in raw materials, suppliers, or manufacturing processes — because even minor modifications can introduce new chemical risks to patients. Regulatory agencies, including the FDA and ISO standards bodies, mandate a documented biological evaluation any time such changes occur, regardless of how small the alteration appears.
