Metris and the 3 R's

Integrated-system.jpgAlthough animal experiments are still needed for drug development Metris has found solutions to reduce the number of experiments and refine animal experimenting.

LABORAS and SONOTRACK offer non-evasive, homecage based, real "night condition" experiments that not only improve quality of research but also enable you to combine presently known experiments into one! This has resulted in avoiding needless use of animals.


The British Coalition for Medical Progress already indicated in 2003 that users of LABORAS were able to refine and reduce their animal experiments. More information can be found in their publication (page 7)
"Animals in Biomedical Research Today: An introduction to the 3R's" (October 2003).

Several other organizations in the Animal Welfare field acknowledge the reduction of animals by using Laboras in animal experiments, such as:
FRAME (Fund for the Replacement of Animals in Medical Experiments)
NCR3 (National Centre for Replacement, Refinement and Reduction of Animals in Research


Reduction of experiments is not only accomplished because we offer the highest number of relevant parameters per animal, but also because raw data remains accessible even after many years (with a typical usage, LABORAS needs 1 DVD for raw data storage per platform per year!). LABORAS experiments are unique as they can be re-done using existing raw data on different behavior modules. No need for experiment approval filling, test-session preparation, use of new animals.

Refinement has been experienced because the fast analysis tools enabled the researchers to alter the course of the experiment based on preliminary results of the first test-sessions.
