Biocompatibility Testing Laboratories

biocompatibility testing and Evaluation - GB/T 16886 / ISO 10993 / USP 88 / ISO 7405, etc.

biocompatibility refers to the ability of a living tissue to coexist with an inert material without adverse reactions.

Generally, it refers to the compatibility between a material and its host, including tissue compatibility and blood compatibility. Biocompatibility should not cause adverse reactions to biological tissues, blood, or other bodily fluids.

One of the fundamental aspects of biocompatibility testing/evaluation is biosafety.

Biosafety refers to the interaction between a material and the human body, ensuring that it is non-toxic, non-allergenic, non-irritating, non-mutagenic, non-carcinogenic, and does not cause adverse reactions in human tissues, blood, or the immune system.

China JJR Biocompatibility Testing Laboratory has obtained certifications from both the China CMA and the United States IAS, and the laboratory operates strictly in accordance with GLP standards. It is recognized by regulatory bodies such as the US FDA, Australia TGA, and Brazil ANVISA. Additionally, it is a recognized partner of international organizations such as UL (United States), CSA (Canada), TUV (Germany), SGS (Switzerland), Intertek (UK), BSI (UK), MEDCERT (Germany), and IMQ (Italy).

China JJR Laboratory provides professional, efficient, and comprehensive biocompatibility evaluations and biocompatibility testing reports.
