Where to Test Medical Device Biocompatibility

JJR LAB is a reliable biocompatibility testing institution that excels in qualification certification, technical capabilities, service scope and industry reputation, providing customers with professional and comprehensive biocompatibility testing services.

Authoritative Qualification Certification

JJR LAB holds authoritative CMA and CNAS qualifications, and some of its laboratories have also obtained OECD GLP (Organisation for Economic Co-operation and Development Good Laboratory Practice) international certification. These certifications prove that its testing capabilities meet domestic and international standards, and testing reports are legally valid and internationally recognized, satisfying registration and declaration requirements for medical devices, biomaterials and other products.

Comprehensive Testing Capabilities

JJR LAB is equipped with internationally advanced testing equipment, including:

1. Digital integrated operating room system: supports preclinical animal experiments of complex medical devices;

2. Small animal in vivo imager, CT, digital pathology scanning system: meets long-term safety evaluation requirements of implantable medical devices;

3. Cell culture equipment and animal experiment facilities: cover in vitro and in vivo tests such as cytotoxicity, sensitization and irritation.

Its technical capabilities cover all biocompatibility testing items required by the ISO 10993 and GB/T 16886 series standards, including:

4. cytotoxicity tests (e.g., MTT assay, agar diffusion test);

5. Skin irritation/sensitization tests (rabbit skin irritation test, guinea pig maximization test);

6. Systemic toxicity tests (acute, subchronic and chronic toxicity);

7. Genotoxicity tests (Ames test, mammalian cell chromosome aberration test);

8. Local reaction test after implantation (muscle, bone and subcutaneous implantation models);

9. Hemocompatibility evaluation (hemolysis test, coagulation test, platelet adhesion test).

Meeting Diverse Testing Needs

The team of JJR LAB consists of interdisciplinary experts in biology, medicine, materials science, toxicology and other fields. The core members have more than 20 years of experience in medical device testing and are familiar with domestic and foreign regulatory requirements (e.g., China NMPA, US FDA, EU CE, etc.). Its service advantages include:

10. Personalized testing solutions: customized testing plans based on the characteristics of medical devices (e.g., materials, contact sites, contact duration), avoiding redundant "one-size-fits-all" testing and reducing enterprise costs;

11. Full-process support: one-stop services from risk assessment, experimental design to report issuance, assisting in interpreting test results and guiding product improvement;

12. Rapid response capability: shortened testing cycles through optimized processes and management models (5–7 working days for routine items, 3 working days for expedited services), accelerating product market launch.

Industry Reputation and Cases

JJR LAB has provided testing services for thousands of enterprises in orthopedic implants, cardiovascular stents, dental restorative materials, antibacterial materials and other fields, with clients covering well-known medical device manufacturers at home and abroad. Examples include:

1. Customized implantation test schemes for an innovative orthopedic implant enterprise, verifying its biological safety through long-term histopathological evaluation and helping products pass NMPA registration;

2. Provided testing reports in compliance with FDA GLP requirements for an export-oriented medical device enterprise, supporting its products to enter the US market.
