World Cup gets all-clear on doping front
No adverse analytical findings have been found among 486 blood and urine samples taken during the Rugby World Cup this year.
World Rugby announced that samples had been taken across all 20 participating sides with 200 in-competition and 268 out-of-competition samples taken.
While none produced a positive test, all samples which included 317 urine and 151 blood samples will be stored for future re-analysis.
The tournament testing programme was an extension of World Rugby's existing anti-doping programme which saw more than 1300 tests taken across teams in and out of competition between January and September.
As part of the Keep Rugby Clean anti-doping education programme more than 600 players and 500 team officials undertook mandatory education before the World Cup tournament.
World Rugby chairman Bernard Lapasset said: "Doping is a major threat to the integrity of sport and World Rugby is committed to a prevention programme of targeted testing and global education to ensure that players at all levels understand the performance and health importance of maintaining a level playing field for all."
Lapasset said while there were no adverse findings before, or during the World Cup, the organisation could not afford to become complacent.
As a result they have increased their budget and are committed to storing samples for potential further analysis.
"Our Rugby World Cup 2015 programme was based on intelligence-led testing and reflects our commitment to ensure that we are ahead of the curve in this area," he said.
The organisation's approach was commended by the director-general of WADA, David Howman.
"With doping in sport very much in the spotlight, it is more important than ever for a sport as global as rugby to ensure it has a programme that combines intelligence-led testing with a strong education initiative such as Keep Rugby Clean.
"World Rugby has taken a positive step in increasing its resources for testing and education, and retaining samples for future analysis as is encouraged under the revised World Anti-Doping Code," Howman said.
