The 3Rs – Replacement, Reduction, Refinement
Learn more about the three guiding principles we apply when using animals in research
The 3Rs – Replacement, Reduction, and Refinement – are a set of guiding ethical principles designed to ensure the humane and responsible use of animals in scientific research.
Implementing the 3Rs is essential not only for ethical and legal compliance but also for promoting high-quality, reproducible science. Researchers, institutions, and regulatory bodies are all responsible for upholding these principles and continuously seeking better alternatives to traditional animal use.
