IOC announces that reanalysis of Krivoshapka’s London 2012 samples resulted in a positive test for banned substance turinabol

The Russian women’s 4x400m relay team are to lose the silver medals they claimed at the London 2012 Olympic Games after team member Antonina Krivoshapka tested positive for a banned substance following sample reanalysis.

The International Olympic Committee (IOC) announced on Wednesday (February 1) that reanalysis of Krivoshapka’s samples from London 2012 resulted in a positive test for dehydrochlormethyltestosterone (turinabol).

Therefore, she is disqualified from both the relay event and the individual 400m, in which she placed sixth.

The Russian 4x400m team – which included Krivoshapka, Yulia Gushchina, Tatyana Firova and Natalya Antyukh – had finished ahead of Jamaica and Ukraine at London 2012, with the Great Britain team finishing fifth.

On Wednesday the IOC also announced the disqualification of Russia’s Vera Ganeeva, who contested the women’s discus event at London 2012, after reanalysis of her samples also resulted in a positive test for turinabol.

“The protection of clean athletes and the fight against doping are top priorities for the International Olympic Committee (IOC), as outlined in Olympic Agenda 2020, the IOC’s strategic roadmap for the future of the Olympic Movement,” read the IOC statement in part. “To provide a level playing field for all clean athletes at the Olympic Games Rio 2016, the IOC put special measures in place, including targeted pre-tests and the reanalysis of stored samples from the Olympic Games Beijing 2008 and London 2012, following an intelligence-gathering process that started in August 2015.”

It added: “The additional analyses on samples collected during the Olympic Games Beijing 2008 and London 2012 were performed with improved analytical methods, in order to possibly detect prohibited substances that could not be identified by the analysis performed at the time of these editions of the Olympic Games.”

The IOC has requested that the International Association of Athletics Federations (IAAF) modifies the London 2012 results accordingly and also considers any further action within its own competence.
