What are the different types of biocompatibility tests?

What are the different types of biocompatibility tests?

Biocompatibility tests assess how materials interact with biological systems. Common types include cytotoxicity, sensitization, and irritation tests.

Can you explain what cytotoxicity tests involve?

Cytotoxicity tests evaluate whether a material is toxic to cells. They typically involve exposing cells to the material and measuring cell viability.

What about sensitization tests?

Sensitization tests determine if a material can cause an allergic reaction. They often involve animal models to assess immune response.

Are there any specific standards for these tests?

Yes, there are standards like ISO 10993 that outline the requirements for biocompatibility testing of medical devices.

How long do these tests usually take?

The duration varies, but most biocompatibility tests can take several weeks to months, depending on the type and complexity.
