The Anti-Doping Bureau of Latvia provides a service - collecting samples of doping control tests (urine or blood samples) during sports competitions or out-of-competitions.
When applying for the control of doping during competitions, the Anti-Doping Bureau of Latvia shall make a selection of the athletes from whom analysis samples will be collected (either on the basis of the results achieved by the athletes in the competition or at random, or by targeting the athlete on the basis of information at the disposal of the Bureau).
In applying for doping control out-of-competition, the Anti-Doping Bureau of Latvia shall carry out tests on athletes of other anti-doping organisations (national anti-doping organisations of other countries, international federations, etc.) who are in the register of athletes to be tested by the relevant organisation (registered testing pool). The tests shall be carried out according to the location information provided by the athlete to his anti-doping organisation.
