Evaluating the Early Operational Performance of the Endocrine Module in the Athlete Biological Passport

In collaboration with various Anti-Doping Organisations and the Paris WADA-accredited laboratory, the International Testing Agency spearheaded the implementation of the Endocrine Module ahead of the Olympic Games Paris 2024. This article presents a data-driven evaluation of its early integration within Athlete Biological Passport (ABP) programs. The assessment of endocrine profile testing follows the complete ABP sample lifecycle, from collection to the submission of reports by the Athlete Passport Management Unit. The article identifies both challenges and opportunities by integrating testing, analytical and ABP perspectives and offers recommendations for the future development of the Endocrine Module. Furthermore, it explores the Endocrine Module's synergy with the Haematological and Steroidal Modules emphasising on key areas for the enhancement of ABP programs as a whole.
