Our Chief Executive Vicky Robinson welcomed the strategy:

"The new government strategy will help to speed up efforts to replace animal research and testing, while also recognising the continued need for high standards of animal welfare where alternative methods currently do not exist."

We use the term new approach methodologies (NAMs) to refer to full and partial replacement approaches for assessing chemical or drug toxicity. Non-animal methods describe full replacement approaches irrespective of the scientific discipline they are used in. Read more: nc3rs.org.uk/replacement-...

The two most common uses of NAMs are to refer to non-animal methods and new approach methodologies. Here we explain the differences between these two terms.
