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 1 and 25 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 passports.
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 (NADOs) and International Federations (IFs). During the Games, the TUE Committee granted 12 TUEs.
Following the recommendations of the World Anti-Doping Agency (WADA), the local organisers used the same sample kits that were used for Rio 2016, developed by Swiss manufacturer Berlinger.
