The World Anti-Doping Agency Director General David Howman has warned of the need to become more efficient in the battle to stop drug cheats in sport.
Howman says he doesn't think anti-doping agencies have the science to track those who dope in a sophisticated manner.
The New Zealand lawyer has told a Paris conference that only dopey dopers are being caught.
While 258,267 tests were carried out across the world last year, only 36 were positive for EPO.
Howman says that's pathetic when the blood booster is the drug of choice for dopers so quality and efficiency of testing must increase.
He also emphasised the importance of punishing doctors, coaches, agents and all others who help sportsmen and women to dope.
