Q: What is biocompatibility?
A: Biocompatibility is the measure of a materials compatibility with the body, be it animal or human. For a product to be biocompatible it must not decompose or put off contaminants that adversely affect the functioning or comfort of the body (either short term or long). Things that require biocompatibility testing are materials which will be implanted or in direct contact with the blood and tissue. Bone implants, heart implants, catheters, diagnostic fluids, external cables, gels and adhesives are all examples of this.
