Chinese national champion tests positive for doping

China's athletics national champion Sun Lu has tested positive for a diuretic, the country's anti-doping body said on Wednesday.

Sun was found using hydrochlorothiazide, a medicine that treats fluid retention and high blood pressure and can be used to cover the traces of other performance-enhancing drugs, the China Anti-Doping Agency told Xinhua.

Sun, who had requested an analysis of her B sample, which still turned out positive, gave up the right for a hearing.

Sun from Henan province won the women's 1,500m title in last year's athletics national championships and the positive test is expected to bring a ban to keep her from this year's National Games, a multi-sport meeting held every four years.
