Thai Badminton Player Pitchamon Opatniputh Was Provisionally Suspended From the Asian Games After a Positive Test
The International Testing Agency said the out-of-competition urine sample was collected in Nagoya on seventeen September, two days before the formal opening ceremony.
Thai badminton player Pitchamon Opatniputh has been provisionally suspended from the Aichi-Nagoya 2026 Asian Games after testing positive for the banned diuretic furosemide, the International Testing Agency (ITA) announced on 21 September 2026.
The 19-year-old's urine sample was collected during an out-of-competition test in Nagoya on 17 September while she was training, two days before the formal opening ceremony. The ITA, acting on behalf of the Olympic Council of Asia, described the result as an adverse analytical finding.
The ITA said the suspension took immediate effect and that she is prevented from competing, training, coaching or participating in any activity during the Games.
Furosemide is listed under diuretics and masking agents on the World Anti-Doping Agency's 2026 Prohibited List. It is classified as a specified substance, is prohibited at all times, and can be used to shed water for rapid weight loss or to mask the presence of other banned substances.
Pitchamon is ranked 18th in the world in women's singles by the Badminton World Federation and third among Thai women.
She has the right to challenge the provisional suspension before the Court of Arbitration for Sport's Anti-Doping Division and to request analysis of her B-sample. The ITA said it would make no further comment while proceedings are ongoing, and the case has not yet been resolved.
