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 while also reinforces a strong dedication to transparency in the fight against doping.
