Reviewed by [Christian Espinosa, Founder, Blue Goat Cyber](/authors/christian-espinosa) Last reviewed May 5, 2026 ## Definition Biocompatibility evaluates how a medical device material interacts with the human body to ensure it does not produce adverse biological responses such as cytotoxicity, sensitization, or systemic toxicity. What the regulation says Regulators like the FDA and notified bodies under the EU [MDR](/terms/mdr-reporting) emphasize biocompatibility as a critical aspect of patient safety. ISO 10993 series is the primary standard for evaluating the biological effects of medical devices, offering a framework for risk management in this area. Manufacturers must demonstrate that their devices do not pose unacceptable biological risks throughout their lifecycle, as outlined in requirements like EU MDR Annex I, Chapter I, Section 10.1. ## What this means in practice Tests are selected per [ISO 10993-1](/terms/iso-10993-1) based on contact category and duration. Material changes typically trigger re-evaluation. ## Examples - A manufacturer of a new cardiovascular stent must conduct extensive biocompatibility testing, including hemocompatibility, due to its direct and prolonged contact with blood. - Before introducing a new adhesive in the assembly of a wound dressing, a company must re-evaluate the dressing's biocompatibility, focusing on potential skin sensitization and irritation. - An orthopedic implant manufacturer must assess the long-term biological response, including degradation product analysis, for their device due to its permanent implantation within the body. Common pitfalls - • Failing to consider the entire manufacturing process and all constituent materials when assessing biocompatibility is a common mistake. - • Assuming prior biocompatibility data for a material is sufficient without considering its processing or final device application can lead to non-compliance. - • Neglecting to re-evaluate biocompatibility after intended changes to material suppliers, manufacturing processes, or sterilization methods is a significant pitfall. - • Not adequately addressing extractables and leachables profiles can result in incomplete biocompatibility assessments. - • Ignoring the potential for long-term biological effects for permanently implanted devices is a serious oversight. ## Frequently asked questions What is the primary standard for biocompatibility? The ISO 10993 series of standards, particularly [ISO 10993-1](/terms/iso-10993-1), provides a comprehensive framework for biological evaluation of medical devices. It guides the selection of appropriate tests based on the nature and duration of device contact with the body. When is biocompatibility re-evaluation necessary? What are common biological endpoints assessed? Does material qualification alone satisfy biocompatibility requirements? ## Related terms Grouped by theme ### Editor's picks · Hand-selected related concepts [ Standards ISO 10993-1 Biological evaluation of medical devices within a risk management process. ](/terms/iso-10993-1) ### Manufacturing & Supply Chain · From this learning path [ Quality & Risk Change Control Formal QMS process for evaluating, approving, and implementing changes that could affect product quality or compliance. ](/terms/change-control?from=manufacturing-and-supply-chain)[ Manufacturing Cleanroom Classes (ISO 14644) ISO 14644 classification of cleanrooms by airborne particulate cleanliness (ISO 1 through ISO 9).
