Overview
- National anti-doping body NADO Italia provisionally suspended Passler after traces of Letrozol were detected, and the Italian federation removed her from the Olympic roster.
- The Biathlon Integrity Unit said it received confirmation of an anti-doping rule violation from NADO Italia and is cooperating with the national authority on the case.
- The sample was collected out of competition in January, reported by multiple outlets as January 26, with B‑sample analysis and disciplinary proceedings still pending.
- Letrozol, an anti‑estrogen banned by WADA since 2008, is used medically in breast cancer treatment and can be associated with masking steroid use; a confirmed violation could bring up to a four‑year ban.
- Prosecutors in Bozen have begun reviewing the matter without opening an investigation into Passler, while Italian sports leaders urge against premature judgment.
