Athlete Biological Passport (ABP)

The Athlete Biological Passport (ABP) is a tool used in sports to monitor an athlete’s biological markers over time. Instead of testing for banned substances directly, it tracks variations in blood parameters, such as hormone levels and blood cell counts, which can indicate doping behaviors. Each athlete has an established baseline profile, and significant deviations may trigger further investigation. The ABP helps ensure fair competition by detecting substance abuse while protecting athletes' privacy and rights, making it a crucial element in anti-doping efforts worldwide.
