NADA Opens Case Against Owen Ansah Over Alleged Test Refusal

Overview

• The German Anti-Doping Agency announced on Friday, July 17, 2026, that it has opened formal proceedings into whether Owen Ansah refused to submit to sample collection.
• NADA says the alleged offence concerns a tester visiting Ansah just before a short-notice Diamond League call-up to Monaco around July 9–10, and Ansah has said he could not give a sample because of travel timing and prior restroom use.
• Ansah says he was tested the next day by the World Anti-Doping Agency on competition day, July 10, and was tested again by NADA the following Monday.
• Under anti-doping rules a refusal to provide a sample is treated like a positive test and can carry up to a four-year ban, though NADA says the regulations do not require an automatic provisional suspension in this case.
• The German athletics federation says it supports NADA and is in close contact with Ansah, who remains a medal prospect for the European Championships in Birmingham while the results-management process continues.
