Here's the story, but doesn't mention if the lab was Chatenay-Malabry.
Even the French Open abandoned that lab for irregularities.
For the life of me, I can't see why TDF sticks with them unless the owner is somebody's brother-in-law or something.
The team contributes a substantial sum [believed to be in hundreds of thousands of euro] to the German NADA and this facilitates the regular testing of its riders by them. It would appear that this was the test which led to the adverse finding for Sinkewitz. (emph mine)
T-Mobile was the team that tried more than anyone to clean house and implement a strong anti-doping program. All winter long, the cycling magazines were touting them and contrasting them with Disco, which had just signed Basso despite allegations of doping. So that makes the Sinkewitz thing even more bizarre.
