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.

Anti-doping organizations can integrate the Athlete Biological Passport into the larger framework of a robust anti-doping program in order to:

  • Identify athletes requiring further attention through intelligent and timely interpretation of Passport data. The ABP provides valuable information that can be used to direct anti-doping activities such as Target Testing or investigations more effectively; and
  • Pursue possible anti-doping rule violations in accordance with World Anti-Doping Code (Code) Article 2.2: Use or attempted use by an athlete of a prohibited substance or a prohibited method.

As the international independent organization responsible for coordinating and monitoring the global fight against doping in sport, WADA has taken the lead in the development of the Athlete Biological Passport concept. WADA’s Athlete Biological Passport Operating Guidelines (ABP Guidelines) were approved by WADA’s Executive Committee and took effect on 1 December 2009. This first version contained a standardized approach to the profiling of individual Athlete Haematological variables for the detection of blood doping. In 2014, the initial system was complemented with the Steroidal Module, which was launched in order to establish longitudinal profiles of an Athlete’s steroid variables measured in urine samples.

Since then, WADA ABP Guidelines have been continuously refined and the ABP approach has been successfully integrated into the anti-doping strategies of International Federation (IF) and National Anti-Doping Agency (NADO) programs, resulting in a significant increase in the number of adverse analytical findings (AAFs) that are a result of targeting by the ABP as well as a number of direct anti-doping rule violations (ADRVs).

WADA continues to develop the ABP in consultation with stakeholders, by refining the present modules as well as adding new ones as they are finalized.
