“It was a long process to test all competitors qualified for the Games. The first series of anti-doping tests started during the Baku Grand Slam and Almaty Grand Prix this May, with the top 16 athletes that were not tested yet by April 1. As the qualification list was not fully determined, the top 16 were chosen as being the most likely to end up as qualified athletes. The testing continued during the World Judo Masters in Guadalajara, Mexico, which was the last Olympic qualification event.
