On behalf of the UCI, the Cycling Anti-Doping Foundation announced that there were no positive doping tests at this year's Tour de France. "All the samples collected were systematically analyzed to detect stimulants and erythropoiesis," said the UCI. (erythropoiesis is the process which produces red blood cells) "Isotope-ratio mass spectrometry (IRMS) was also analyzed in a certain number of samples, in particular to detect testosterone abuse and its precursors." The sampling exceeded that of last year's Tour, 719 blood and urine samples were taken. This is great news for professional cycling. Hopefully the sport can start distancing itself from the negative stereotype of drug use.
