Urine and blood doping tests are carried out in anti-doping laboratories accredited by the World Anti-Doping Agency every three months. Doping tests are not checked in any laboratory, because it is a high-tech and very complicated process. The number of such laboratories does not exceed 30 in the world, and their list is available on the website of the World Anti-Doping Agency. Doping tests are definitely checked anonymously, that is, without knowing which athlete this or that doping test belongs to. For him, each doping sample is given a separate seven-digit secret code before it is sent to the laboratory. Anti-doping laboratory does not know this code. It can be known by the athlete himself and the responsible staff of the International Federation and national anti-doping agencies who have the right to access the ADAMS system.
Therefore, the idea that some anti-doping laboratories knowingly search for prohibited substances in the composition of the athlete's doping tests is unfounded.
