The Athletics Integrity Unit (AIU) was founded by World Athletics in 2017 to combat doping and address other forms of ethical misconduct in the sport of athletics.[1] The Monaco-based organization operates independently from World Athletics to fulfill World Anti-Doping Code requirements.[2] It is currently headed by Brett Clothier.[3]
The organization collected more than 3800 samples from athletes in the first six months of 2021 in advance of the 2020 Summer Olympics.[4] In 2023, AIU announced new efforts to establish a "blood steroid passport" to better detect the presence of steroids, more commonly used in sprinting and throwing events, through blood serum and endocrine testing.[5]
AIU argues that the number of doping bans in athletics indicates that other sports are not robustly testing athletes.[6]
