Cyclingnews reported that Iban Mayo's B sample from the Tour de France was opened yesterday in the University of Gent, Belgium.

This is noteworthy for two reasons:

1. It isn't the Châtenay-Malabry laboratory that tested the A sample
2. It isn't in France.

Until now, it was considered fine to do A and B testing at the same laboratory, but not for Mayo? Why the sudden change in procedure? This is a welcome change, but I would love to know why the change was made.

As you say, welcome change. Long past time for UCI/WADA to use the B sample as an opportunity for adding to, rather than detracting from, the credibility of testing.

I belive that Herras' samples were tested in different labs. I could possibly be not recalling that correctly though.
