Valieva tested positive for the banned substance trimetazidine, designed to prevent angina, at the Russian national championships in December 2021 when she was 15. Her team has said the positive test could have been due to a mix-up with her grandfather's heart medication. The delay in the medal allocation has angered competitors, with Vincent Zhou, one of the skaters on the silver medal-winning U.S. team, saying that the global anti-doping system was"failing athletes".
