New steroid profiling test ready
The World Anti-Doping Agency says it is introducing a new technique for urine tests next year that will help catch athletes who take steroids.
WADA calls it "the twin" of the blood profiling system used by around 35 sports in athletes' biological passport. It will allow anti-doping authorities to build a profile of a person's steroid levels from urine samples and to identify any changes -- in a similar way that changes in blood may indicate doping.
WADA says the new technique will particularly target testosterone and will "complement" the biological passport. It can be used from Jan. 1.
WADA has also developed a mobile App that allows athletes to give their whereabouts through their cellphones or other devices so they don't miss out-of-competition tests.
