Athlete Biological Passport

The fundamental principle of the Athlete Biological Passport (ABP) is to monitor selected biological variables over time that indirectly reveal the effects of doping rather than attempting to detect the doping substance or method itself.

World Curling integrates the Athlete Biological Passport into the larger framework of their robust anti-doping program. Questions and Answers on the ABP can be found here:  https://www.wada-ama.org/en/questions-answers/athlete-biological-passport
