The International Testing Agency (ITA), which oversees World Aquatics' anti-doping programme, collected 1,845 samples from 911 athletes of 82 nationalities in the second quarter of 2025.

Out-of-competition testing accounted for the vast majority of samples, with 1,638 collected outside of competition periods. In-competition testing yielded an additional 207 samples.

Of the total samples collected in Q2 of 2025:

  • 1,369 Urine
  • 476 Blood

For reference, the World Aquatics' anti-doping programme overseen by the ITA collected 1,413 samples from 680 athletes of 63 nationalities in the first quarter of 2025.

World Aquatics had a comprehensive and rigorous anti-doping testing programme before the World Aquatics Championships – Singapore 2025, which will be reflected in the Q3 anti-doping statistics. To find out more about the anti-doping programme, check out this press release. Additionally, during the World Aquatics Championships in Singapore, World Aquatics and ITA offered media a rare look inside the doping control in-competition testing process that was in place during the 2025 Worlds.

These figures reflect a coordinated international effort to promote clean sport and uphold fair play. The continued increase in both volume and geographic reach of testing underlines World Aquatics’ commitment to safeguarding the integrity of aquatic sports. It also reinforces a strong dedication to transparency in the fight against doping.
