A broad definition of Humane endpoint is a concept for continuous refinement of animal studies (Hendriksen et al., 2010).

This broad definition is aligned with the 3R principles (Balls et al., 1995, Russell and Burch, 1959).

Continuous improvements or refinement is embedded in the directive 2010/63 (European Commission, 2010)

  • Article 4.3 Member States shall ensure refinement of breeding, accommodation and care, and of methods used in procedures, eliminating or reducing to the minimum any possible pain, suffering, distress or lasting harm to the animals.

Many or few endpoint criteria

Some authors stress that endpoints can rarely be generalized. Using too many and too general endpoints for scoring is labor intensive. Researchers might be required to evaluate variables that might appear arbitrary or unrelated to the animal’s condition. Compliance may be increased if the measurement of the variables is related to research objectives. Other authors underline that humane endpoint cannot rely on a single variable, suggesting to use a combination of variables and recommend a combination of assessment parameters for a robust welfare assessment in laboratory animals   and early predictor of death. For example, the combined reduction of body weight and body temperature, has shown to be a reliable predictor of death in studies including:
