in 2015, in the wake of revelations of widespread doping in athletics, radcliffe said that, unlike some other prominent british athletes, she would not be releasing her blood-test history, and discouraged other athletes from doing so. she was later indirectly identified as a suspected doper by mp jesse norman during a parliamentary inquiry into blood doping. in response, radcliffe issued a statement in which she "categorically denied" cheating in any form and said she has "nothing to hide". shortly afterwards, her three suspect test results were leaked, though radcliffe still refused to release her complete blood-test history. in late november 2015, the iaaf declared that the accusations were "based on the gross misinterpretation of incomplete data". the uk anti doping agency, having received radcliffe's blood test history via the iaaf, stated that "ukad has come to the same conclusion as the iaaf review that there is no case to answer". it is likely that the first suspicious off-score was caused by faulty equipment. the third suspicious off-score was the direct result of an altitude training trip in kenya with mo farah and other british athletes.

bullet::::- tyler hamilton won the gold medal in the men's individual time trial at the 2004 summer olympics in athens. that medal was placed in doubt on 20 september 2004, after it was revealed that he had failed a test for blood doping (receiving blood transfusions to boost performance) at the olympics. two days after the announcement of his positive test result at athens, the ioc announced that hamilton would keep his gold medal because results could not be obtained from the second, backup sample. the athens lab had frozen the backup sample, which made it impossible to repeat the blood doping test. hamilton also tested positive for blood doping at the 2004 vuelta a españa, where he won the april 8 stage. in april 2005 he was banned for 2 years for blood doping. the uci summary of 'decisions on anti-doping rule violations made in 2006' stated that for homologous blood transfusion he would be sanctioned to "disqualification and ineligibility for 2 years".
