In 2007, the National Research Council released a report entitled Toxicity Testing in the 21st Century: a Vision and a Strategy. That report proposed a new paradigm for toxicity testing that envisions evaluation of biologically significant perturbations in key toxicity pathways using new methods in computational biology and a comprehensive array of in vitro tests based on human biology. The new paradigm was developed to provide broad coverage of chemicals, mixtures, outcomes, and life stages; to reduce the numbers of animals used in testing and the cost and time associated with testing; and to develop a more robust scientific basis for assessing health effects of environmental agents.
