The International Testing Agency (ITA), which oversees World Aquatics' anti-doping programme, collected 1,403 samples from 894 athletes of 104 nationalities in the third quarter of 2025.

With the World Aquatics Championships - Singapore 2025 taking place during Q3 of this year, in-competition testing accounted for the vast majority of samples, with 843 collected during competition periods. Out-of-competition testing yielded an additional 560 samples.

Of the total samples collected in Q3 of 2025:

  • 1,033 Urine
  • 370 Blood

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 2025 Worlds in Singapore, World Aquatics and ITA offered media a rare look inside the doping control in-competition testing process.

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