Is Delayed Testing Possible?

In the wake of the latest Lance Armstrong doping allegations coming out of France, the director of Canada's top anti-doping lab wonders if delayed testing is even possible.

"EPO is a protein hormone and it is not stable in urine, even when kept frozen," said Doctor Christiane Ayotte. "This has long had implications for any plan we've had to keep samples and specimens for long periods of time with the hope that we might, some day, retest those samples for a new substance."
