Twenty-eight athletes face disciplinary action over historical doping offences, the International Association of Athletics Federations has announced.
The world governing body said the retesting of anti-doping urine samples from the 2005 and 2007 World Championships in Helsinki and Osaka had turned up 32 adverse findings from 28 athletes.
The IAAF said it could not name any of the athletes yet due to the "legal process" but a "large majority of them are retired, some are athletes who have already been sanctioned and only very few remain active in sport."
ITV News understands none of the 28 athletes are British and that six of them are still competing. Sports Editor Steve Scott says medals from the 2005 and 2007 World Championships could be redistributed as a result of the findings:
Up to 10 medals from 2005/7 World Champs likely to be withdrawn and redistributed. Could 'benefit' high profile British athletes.
The IAAF said that "none of the athletes concerned will be competing in Beijing", where the 2015 World Championships will begin on August 22.
The 2005 event was staged in Helsinki, with Osaka in Japan hosting two years later.
The IAAF added that its retesting had begun in April, "well before the most recent allegations made against the IAAF by the [German broadcaster] ARD and The Sunday Times".
ITV Sports Editor Steve Scott reports.
London Marathon chief executive Nick Bitel has said race organisers are "very concerned" by allegations in the Sunday Times that seven winners in a 12-year period recorded suspicious blood scores.
The newspaper has published fresh allegations following its analysis of drugs test data from 2001 to 2012.
It said the winners of 34 major marathons around the world - one in four - during the period should have faced censure or investigation because of their test results, with those athletes collecting more than £3million in prize money.
We believe there are people in our sport who are cheating and everyone has a part to play to protect those who are not.
We continue to be at the forefront of anti-doping measures for marathon runners as we are determined to make marathon running a safe haven from doping but we cannot do it all on our own and rely heavily on the IAAF.
We are therefore very concerned by the allegations made in the Sunday Times today and we will be discussing the implications of the allegations with the IAAF.

Olympic champion Jessica Ennis-Hill has announced on her Instagram account that she is making herself available for selection for the World Championships in Beijing.
Mo Farah received a rapturous reception as he won the 3,000m at the London 2012 Anniversary Games.
The double Olympic Champion was cheered from the moment he took to the track to crossing the line in seven minutes 24.66 seconds.
The 32-year-old hit the front with two-and-a-half laps to go before striding away down the home straight to claim a commanding triumph at the Sainsbury's Anniversary Games.
The Londoner's time was the fastest in the world this year and another confidence boost as he builds up to the defence of his 5,000 and 10,000m titles at the World Championships in Beijing next month.
Farah has come in for heavy scrutiny after it was alleged Salazar, head coach at the Nike Oregon Project in Portland, had violated anti-doping rules.
The Briton has not been accused of any wrong-doing, while Salazar himself has strongly denied the allegations.
Usain Bolt will return to London's Olympic Stadium after being announced as one of the headline acts for the Sainsbury's Anniversary Games.
The world record holder for both the 100m and 200m will compete on the Friday evening in Stratford - just as he did two years ago for the first anniversary of his Olympic success.
Bolt, now 28, took three Olympic gold medals on the track in 2012 and the Jamaican is looking forward to competing in the stadium once again.
"London is a special place where I love to compete and I am looking forward to the Sainsbury's Anniversary Games on July 24," he said.
