The FRAS system with its d-ROMs and PAT tests is the most important system in the world for scientifically measuring oxidative stress in a complete manner. Research centres and universities across the globe have chosen it and use it as their official system for measuring oxidative stress.

For this reason the Carr. Unit®, which is used to express the values ​​of free radicals, is considered the official unit of measure by the international scientific community.
