Armstrong (above), who is due to return in the Tour Down Under in Australia in January, will fight against having his old samples re-tested. "Nobody in their right mind would take that test," he said.
"Something might have been put in it and your life, your credibility, depends on it. I'm all for drug controls but if the athlete cannot defend himself, what kind of kangaroo court is that?"
Meanwhile, Italian Riccardo Ricco has appealed his two-year doping ban to the Court of Arbitration for Sport.
Ricco was banned by the Italian Olympic Committee last month for doping during this year's Tour de France in which he won two stages.
