The Working Party of National Coordinators of the Test Guidelines Programme (WNT) of the Organisation for Economic Co-operation and Development (OECD) has called for “urgent mobilisation of national and regional resources for the demonstration of reproducibility and reliability of methods developed in single laboratories.” In a statement, the WNT notes a lack of funding for studies to demonstrate transferability and reproducibility of a new chemical safety testing method outside the developer’s laboratory. Lack of funding for such validation studies is hindering progress toward implementation of new methods with the potential to reduce use of laboratory animals and better protect human health and the environment.
