Giro champion Danilo Di Luca also gave an irregular doping test, after stage 17 to Monte Zoncolan. The test, given spontaneously hours after the routine test Di Luca gave for being race leader at the time, reportedly showed hormone levels like "those of a child," causing anti-doping authorities to suspect that Di Luca was using some means to cover the presence of banned substances. These unusual levels were not present in the routine test, leading to suspicions that Di Luca had received an autologous blood transfusion between the two tests. A CONI commission later cleared Di Luca on the basis of insufficient evidence to conclude that he had doped.
