Hold the Mayo - again

Poor Iban Mayo - he's a doper one moment (A-sample positive) and cleared the next (B-sample negative). Not satisfied, the UCI are retesting his B-sample. Do we continue testing until we get the result we want? Or should we indeed trust some labs over others? What ever happened to trusted lab standard accreditation?

The counter analysis of Iban Mayo's B sample will be carried out today in the French Châtenay-Malabry laboratory, regardless of whether the Saunier-Duval Prodir rider or a representative is present, according to todociclismo.com. The French laboratory received world wide attention after its practices were scrutinised during an American arbitration hearing over the positive test returned by Floyd Landis, who won the 2006 Tour de France before being striped (sic) of the title following the hearing.
