WADA Athlete Biological Passport The Athlete Biological Passport (ABP) is a longitudinal monitoring program developed by the World Anti-Doping Agency that detects effects of doping by tracking individual athletes' biological markers over time. It complements traditional analytical testing used by the International Olympic Committee, Union Cycliste Internationale, Fédération Internationale de Football Association, International Association of Athletics Federations, and other international federations to improve detection of prohibited methods and substances. The ABP framework integrates clinical hematology, steroid profiling, and statistical approaches pioneered in sport medicine, sports science, and forensic toxicology.
The ABP was formally adopted after collaborative work involving the World Anti-Doping Agency, International Olympic Committee, Union Cycliste Internationale, International Association of Athletics Federations, and national anti-doping organizations such as the United States Anti-Doping Agency, UK Anti-Doping, Australian Sports Anti-Doping Authority, and Agence française de lutte contre le dopage. Early influential actors included laboratory networks like the World Anti-Doping Agency-accredited laboratories in Montreal, Cologne, and London, and research groups at institutions such as University of Lausanne, University of Ferrara, and Vrije Universiteit Amsterdam. The initiative aligned with policy actions by the Court of Arbitration for Sport, the International Testing Agency, and national courts in cases involving athletes from Russia, Kenya, Ethiopia, Italy, Spain, and Colombia.
The ABP uses serial measurements of biomarkers including hemoglobin concentration, reticulocyte percentage, OFF-score, and steroid ratios to infer blood manipulation and steroid use. Laboratories accredited by the World Anti-Doping Agency apply methods from clinical hematology instruments produced by manufacturers like Sysmex, Abbott, and Beckman Coulter, and mass spectrometry platforms from Thermo Fisher Scientific and Waters. The hematological module and steroidal module rely on Bayesian statistics, adaptive models, and algorithms developed in collaboration with statisticians at École Polytechnique Fédérale de Lausanne, University of Oxford, and University of Copenhagen. Biomarkers tracked include erythropoietin-related indices monitored alongside data from the International Association of Athletics Federations' Athlete Passport Management Unit, cycling anti-doping programs used by Team Sky, and football screening programs run by UEFA and CONMEBOL.
Governance of the ABP involves the World Anti-Doping Agency, national anti-doping organizations, international federations such as the International Olympic Committee, Fédération Internationale de Ski, Fédération Internationale de Natation, and federations for weightlifting and wrestling. The Athlete Passport Management Unit oversees data management with support from laboratories accredited by the World Anti-Doping Agency, independent experts from institutions like the University of Lausanne and King's College London, and oversight from panels including members appointed by the Court of Arbitration for Sport and the International Testing Agency. Policy decisions have been shaped by parliamentary inquiries in the United Kingdom, the McLaren Report, and investigations involving the Russian Anti-Doping Agency and the International Olympic Committee.
The ABP has enabled sanctions against athletes in cycling teams such as Team Sky, Tinkoff–Saxo, and Movistar, as well as competitors in athletics, weightlifting, and football. Adjudications have taken place before the Court of Arbitration for Sport, national courts in France, Italy, Spain, and Switzerland, and disciplinary tribunals within federations like FIFA, UEFA, and World Athletics. High-profile cases involving riders from the Tour de France, marathoners from the London Marathon and Boston Marathon, and lifters at the Olympic Games and Commonwealth Games illustrated the ABP's role alongside laboratory positives reported by WADA-accredited labs in Montreal, Cologne, and Singapore.
Validation studies supporting the ABP derive from research groups at institutions including the University of Florence, University of Copenhagen, Vrije Universiteit Amsterdam, and King’s College London, with methodological contributions from statisticians associated with École Polytechnique Fédérale de Lausanne and University of Oxford. Limitations include biological variability influenced by altitude exposure as studied by the International Olympic Committee, illness episodes documented by the International Association of Athletics Federations, and confounding effects from therapeutic use exemptions regulated by the World Anti-Doping Agency. Challenges in steroidal module interpretation have prompted methodological refinements by laboratories in Cologne and Lausanne and prompted legal scrutiny by defense teams represented at the Court of Arbitration for Sport and national Supreme Courts.
Legal debates about the ABP have engaged the Court of Arbitration for Sport, European Court of Human Rights discussions in national contexts, national legislatures in Australia and the United Kingdom, and athletes represented by counsel before tribunals in Italy, Spain, and France. Ethical questions involve privacy protections overseen by national data protection authorities, consent frameworks used by the International Testing Agency, and the balance between public interest in fair play espoused by the International Olympic Committee and individual rights invoked by athletes appearing before disciplinary panels and civil courts.
Notable outcomes include sanctions against cyclists from teams implicated in doping scandals adjudicated by the Court of Arbitration for Sport and national anti-doping agencies; athletics cases resulting in medal reallocations by the International Olympic Committee and World Athletics; weightlifting disqualifications at the Olympic Games and World Championships; and national high-profile prosecutions influencing policy in Russia, Kenya, Ethiopia, and the United States. Investigations and reports such as the McLaren Report, the Independent Commission findings for Russia, and national inquiries in the United Kingdom and Australia shaped implementation, with science contributions from the University of Lausanne, Vrije Universiteit Amsterdam, and University of Oxford informing ongoing refinements.
