The disclosure came as the governing body announced that two athletes - Sara Moreira of Portugal (pictured above right) and Hee-Nam Lim of South Korea - had returned adverse analytical findings from urine tests at the Championships.

Both findings - which were for methylhexaneamine, a prohibited stimulant - have been confirmed by B-sample analysis and both athletes provisionally suspended, pending the outcome of disciplinary hearings.

Much of the focus of the IAAF anti-doping programme in Daegu was on collecting blood samples, primarily for profiling purposes in connection with the athlete biological passport.

According to the IAAF, a total of 1,849 blood samples were collected in all.

The body said that samples were analysed on-site in Daegu for a first haematological screening.

They had now been transferred to the World Anti-Doping Agency (WADA)-accredited laboratory in Lausanne where further analyses were ongoing "including, in specific cases, for EPO and Growth Hormone".

IAAF President Lamine Diack said he was "delighted to report that the testing programme in Daegu was an unprecedented success in terms of the number of samples collected".

He added: "We were committed in Daegu to launching the Athlete Biological Passport in athletics and in this regard, in addition to our regular world championships testing programme, we were successful in taking a blood sample from every accredited athlete in Daegu which was a remarkable achievement."
