It works in conjunction with five International Standards. The goals of this standarts are improved consistency among anti-doping organizations in various areas: testing; laboratories; Therapeutic Use Exemptions (TUEs); the List of Prohibited Substances and Methods; and the protection of privacy and personal information. In Turkey, there is a doping control center called the Turkish Doping Control Center (TDKM), a Hacettepe University unit The aim of this center is to; enable young people to do sport healthily, prevent unfair competition in sports, make doping and other chemical analyses, conduct fundamental and practical researches and projects, develop new techniques in this regard, collect data in light of the aims of the center, offer consultation services.
