On the back of a record targeted pre-Games anti-doping testing programme, doping control was intensified during the Olympic Winter Games to strengthen the integrity of sport and provide a level playing field for all clean athletes.
The Global Association of International Sports Federations (GAISF), in collaboration with the PyeongChang 2018 Organising Committee (POCOG), oversaw the doping controls and results management during the Olympic Winter Games, on behalf of the IOC, to ensure an independent overview of the anti-doping programme.
In total, 3,149 anti-doping tests were conducted during PyeongChang 2018, making it the most robust anti-doping programme in the history of the Olympic Winter Games. Of these tests, 1,393 were in-competition, and 1,756 were out-of-competition.
Of the 2,963 accredited athletes, 1,615 were tested at least once, representing 54 per cent, with the majority being tested out-of-competition.
Of the 3,149 samples collected between 1st and 25th February 2018, and as registered in the Anti-Doping Administration Management System (ADAMS), 2,261 were urine samples; 594 were blood samples; and 294 were blood passport tests.
In the lead-up to the Games, the Therapeutic Use Exemption (TUE) Committee, appointed by the GAISF, reviewed and formally recognised 24 TUEs granted by National Anti-Doping Organisations and International Federations. During the Games, the TUE Committee granted 12 TUEs.
