SD Worx rider Chantal van den Broek-Blaak tested positive for a banned diuretic during the World University Championships in 2008. However, the positive test result was reportedly lost which meant that the Dutchwoman was never sanctioned for it. 

According to a report by Dutch newspaper AD, the Dutch rider returned a positive test for Furosmide, a drug used to treat fluid build-up due to heart, liver and kidney problems, after finishing second amongst an all Dutch top five at the event in Nijmegen 14 years ago. She was never sanctioned or banned for the test result.
