Athlete biological passport: longitudinal biomarkers and statistics in the fight against doping

Arh Hig Rada Toksikol. 2024 Mar 29;75(1):24-31. doi: 10.2478/aiht-2024-75-3793. eCollection 2024 Mar 1.ABSTRACTAs novel substances, short time windows, and limits of detection increasingly challenge direct methods of doping detection in sports, indirect tools inevitably take a greater role in the fight against it. One such tool is the athlete biological passport (ABP) - a longitudinal profiling of the measured haematological and biochemical biomarkers, combined with calculated scores, against the background of epidemiological data crucial for doping detection. In both of its modules, haematological and steroidal, ABP parameters are analysed with the Bayesian adaptive model, which individualises reference and cut-off values to improve its sensitivity. It takes into account the confounding factors with proven and potential influence on the biomarkers, such as race and altitude exposure. The ABP has already changed the fight against doping, but its importance will further grow with the new modules (e.g., endocrinological), parameters (e.g., plasma volume-independent parameters), and complementing indirect methods (e.g., transcriptomic).PMID:38548376 | PMC:PMC10978099 | DOI:10.2478/aiht-2024-75-3793
