Alternative Toxicology

Sidebar Image

Eurofins BioPharma Product Testing is committed to the advancement of animal welfare and we encourage others to include human concern for animals as a core aspect of corporate social responsibility.

That is why Eurofins BioPharma Product Testing is a leader in safety testing without animals and deeply committed to the principles of the 3 R’s of Replacement, Reduction and Refinement.

Our evaluation methods incorporate a unique approach that lead to improved prediction of human results.

Our service portfolio includes methods for replacing the use of animals to evaluate acute systemic toxicity, skin and eye irritation and skin allergenicity and also reducing the use of animals for repeated-dose toxicity, carcinogenicity and reproductive toxicity.

Eurofins BioPharma Product Testing works closely with independent scientists and regulatory agencies to adopt methods to satisfy various regulations. We are proactive in the development and use of in vitro methods partnering researchers and clients in prevalidation and validation studies.
