It is claimed by Russian whistleblower Grigory Rodchenkov that her positive sample (found with the doping compound GW1516) was in fact one from her 2012 Olympics mistakenly substituted for a further positive test result by the state run-doping programme.

He claims that she had at least 2 positive findings that went unreported and that this one was reported only because it was witnessed by non-Russian experts.
