Are there alternatives to using animals in research and testing?

It has proved very difficult to develop non-animal methods to replace the use of animals in research and testing. Most progress has been made in the replacement of animals in safety testing. Once non-animal methods have been developed and validated, and are accepted by the regulatory authorities world wide, then they must be used in preference to the animal tests. Animal experiments are just one method in biological and medical research - research can also be done using cells, tissues, people, and high tech equipment. Some people regard these methods as alternatives, but they are really complementary methods that are used alongside animal research to answer different sorts of questions. Animal research and testing accounts for a small propoortion of all biomedical research and testing.
