What does 'actual severity' refer to in animal research?

'Actual severity' in the context of animal research refers to the highest level of suffering recorded at any point during an experiment. This concept is significant because it assesses the real impact of research procedures on the animals involved. Understanding the actual severity helps researchers and regulatory bodies ensure that the welfare of the animals is prioritized and that suffering is minimized throughout the study.

Accurate measurements of actual severity are essential for ethical review processes and compliance with regulatory standards. It enables researchers to make informed decisions regarding animal use, refine their methodologies, and potentially reduce the severity of procedures. This understanding is crucial for advancing humane practices in research and ensuring that ethical standards are upheld.
