Home » Frequently Asked Questions About In Vitro Irritation and Cytotoxicity Testing
Biocompatibility assessments are a battery of tests performed to evaluate a product, medical device, or other material for the risk of biological hazards. The first test performed is typically a cytotoxicity evaluation. This is done by preparing an extract of the sample to treat a monolayer of healthy mammalian cells in vitro. Results of this assay can indicate the potential toxicity risk a product carries without testing on animals.
Irritation is a localized non-specific inflammatory response to a single, repeated, or continuous application of a substance or material. The in vitro irritation test involves an extraction in physiologically relevant solvents. These extracts are applied to a reconstructed human epidermis model which contains the major layers of cells that are found in a true human epidermis. Death of the cells in this model after exposure to the extracts collected from a product indicate that an irritating substance was leached off the material and poses a risk of adverse reactions in the end user.
