The sport's world governing body says a total of 1405 doping controls were carried out at the IAAF World Championships in Beijing

The International Association of Athletics Federations (IAAF) has published details on what the sport's world governing body describes as an "extensive" anti-doping programme in Beijing.

A total of 1405 doping controls are said to have been carried out at the IAAF World Championships in the Chinese capital, including:

- 662 blood tests for screening purposes in the context of the Athlete Biological Passport

- 161 blood tests for the detection of Human Growth Hormone and Erythropoiesis stimulating agents

- 54 urine tests conducted out-of-competition

- 528 urine tests conducted at the stadium, 239 of which will be specifically analysed for EPO and related substances

"The doping control programme implemented by the IAAF in Beijing was the largest implemented in a single sporting event BY ANY SPORT since the IAAF World Championships in Moscow two years ago," read an IAAF statement in part.

"As forecast by the IAAF prior to the championships, the programme was highly targeted in nature," the statement continued. "Thousands of samples were collected out-of-competition in the lead-up to the event, and the IAAF then implemented an intelligence-led programme in Beijing which will see the samples frozen and stored for future re-analysis as science and technology progresses."

So far, two athletes are reported by the IAAF to have recorded positive tests. The provisional suspension of the two Kenyan athletes, Joyce Zakary and Koki Manunga, was announced on August 26.

"Should any of the remaining samples be reported as positive, the IAAF will make a public announcement when the rules allow," read the statement.
