Introduction: In the field of medical implants, the biocompatibility test report is the "pass" for whether medical titanium plates can be used safely. This article will analyze in detail the content, standards, and clinical significance of the Biocompatibility test report for medical titanium plates to help you fully understand this important document related to surgical safety.
What is a biocompatibility test report?
The biocompatibility test report is a professional document that comprehensively evaluates the interaction between medical titanium plates and human tissues. It verifies through a series of standardized Biocompatibility test report for medical titanium plates that titanium plate materials will not cause adverse reactions after implantation in the human body, ensuring the safety of clinical applications.
What are the key items included in the test?
- Cytotoxicity test (ISO 10993-5)
Evaluate the effect of materials on cell growth
Require cell survival rate ≥ 70%
- Sensitization test (ISO 10993-10)
Detect the possibility of materials causing allergic reactions
Verified by the guinea pig maximization test
- Irritation and intradermal reaction test (ISO 10993-10)
Evaluate the degree of irritation of materials to tissues
Require the reaction level ≤ level 1 (mild)
- Acute systemic toxicity test (ISO 10993-11)
Detect the effect of materials on the whole body
Require no toxic reaction
- Genetic toxicity test (ISO 10993-3)
Evaluate whether the material may cause gene mutations
Pass the Ames test and other tests
Testing standards and certification requirements
International standards:
- ISO 10993 series (biological evaluation of medical devices)
- ASTM F67/F136 (standard for medical titanium materials)
Domestic certification:
- Registration requirements of the National Medical Products Administration (NMPA)
- YY/T 0640-2016 (General requirements for metal implants)

Frequently asked questions
Q1: Are the testing standards for imported titanium plates and domestic titanium plates the same?
A: The basic requirements are the same, but the specific test items may be slightly different.
Q2: How long is the validity period of the Biocompatibility test report for medical titanium plates?
A: Generally 3-5 years, and re-testing is required if expired.
Q3: Do small titanium plates need to be tested separately?
A: The same material series products can share the test report.
Conclusion:
The Biocompatibility test report for medical titanium plates is an important proof of the safety of medical titanium plates. It is recommended that patients understand the test results of the titanium plates used before surgery, and doctors should also pay attention to the integrity and timeliness of the test report when selecting implants. Only titanium plates that have passed strict testing can ensure the safety and success of the surgery.
