Possibilities For Refinement And Reduction: Future Improvements Within Regulatory Testing, Martin L. Stephens, Kathleen Conlee, Gina Alvino, Andrew N. Rowan

Andrew N. Rowan, DPhil

Approaches and challenges to refining and reducing animal use in regulatory testing are reviewed. Regulatory testing accounts for the majority of animals reported in the most painful and/or distressful categories in the United States and Canada. Refinements in testing, including the use of humane endpoints, are of increasing concern. Traditional approaches to reduction (e.g., improving experimental design) are being supplemented with complementary approaches, such as the use of tier testing to eliminate some chemicals prior to in vivo testing. Technological advances in telemetry and noninvasive techniques will help decrease either the demand for animals in testing or animal suffering. Further …
