IOC to retest frozen samples using new method

Test of frozen samples led to positive cases that were previously undetected


The International Olympic Committee (IOC) will retest frozen samples from previous Games after an improved testing method led to hundreds of positive cases that went undetected, according to a German television report.

Laboratories in Cologne and Moscow have found traces of anabolic steroids in hundreds of urine samples using the new testing method, German broadcaster ARD said in a statement.

The revelation has surprised the chairman of the IOC’s medical commission Arne Ljungqvist, who will recommend retesting of frozen urine samples from previous Olympic Games.

“This case is a good example of the necessity of performing retests on Olympic doping samples. I would certainly conduct retests here. We have the mandate for that, after all,” he was quoted as saying in the statement from the broadcaster.

The World Anti-Doping Agency (Wada) has also asked the IOC to act while recommending retests.

“We can only recommend the retests, but we don’t lecture. But we believe that information of this kind should be passed on to the IOC,” David Howman, director general of Wada, was quoted as saying.

“If we make a sensible recommendation based on sensible facts I think that others will implement it.”

The samples would have gone undetected a year ago as detection windows for the substances were significantly shorter with the conventional detection method, officials from the lab said.

“With this detection method, 100 urine samples have now tested positive that would previously have turned up negative,” Grigory Rodchenko, head of the Mosow control laboratory, added.

The IOC can re-test athletes’ samples from its own events up to eight years after the Games and can sanction them.
