Cyclingnews has a written that there will be no re-testing of samples taken in the Giro, because:

"The Giro d'Italia has already made the necessary checks," said race director Angelo Zomegnan to the Apcom news agency on Thursday. "The labs and the UCI have told us these tests were done and nothing was found that could be taken as suspect. It's useless to ask for more (tests)."

The Tour retested its samples with a greater degree of scrutiny.  So, when were the Giro CERA tests performed, and did they bear the same scrutiny on their samples?

It's also interesting that we made it all the way until now to learn that they tested for CERA in the Giro.  What is the motivation for the secrecy?  Wouldn't it be more effective to announce that this, too, is not an option?  Or, does fostering the dopers' belief in undetectability keep them from, e.g., using micro-doses or switching to another drug?

BTW, I posed the question about when the other GTs will retest in the Schumi-busted post and only Celestn got it right:

Well I do.. [think the took blood for tests at the Giro and Vuelta] ..Having seen the Bordry TV interview, he clearly stated that this was/is a team effort from both organisation and lab. I 100% believed him, I also had other reliable personal contact stating that.

Food for thought.
