"All the samples collected were systematically analysed to detect stimulants and erythropoiesis," said the UCI, the latter being the process which produces red blood cells.

"Isotope-ratio mass spectrometry (IRMS) was also analysed in a certain number of samples, in particular to detect testosterone abuse and its precursors."

A total of 719 blood and urine samples were taken on this year's Tour, compared to 622 a year ago, with the testing carried out at a laboratory in France.
