title: Detection of doping with rhGH: excretion study with WADA-approved kits.
abstract: The detection of recombinant human growth hormone (rhGH) doping using the World Anti-Doping Agency (WADA) approved kits is reported in this research. Twenty-five young male students were selected and divided randomly into two groups with six belonging to the placebo and nineteen to the administration group. Thirteen volunteers in one group were administered with a Chinese preparation of rhGH while six volunteers included in the other group were given rhGH made in Switzerland. Both preparations were administered at a dose of 0.1 IU/kg body weight, one injection per day for 14 consecutive days. Blood samples were collected using WADA guidelines and all blood samples were analyzed with WADA-approved Kits 1 and 2. The time window for detection of rhGH doping using WADA-approved kits and criteria are discussed. Based on the comparison of the data obtained from this excretion study and from our routine (Chinese population as reference), consideration of the recent WADA criteria for rhGH AAF (Analytical Adverse Findings) is reported statistically. A comparison of data obtained from the two sample groups administered with pharmaceutical preparations, one Chinese rhGH (GenHeal®, S19990019, 1.6 mg (4 IU), Shanghai, China) obtained from prokaryotic cells and the other (Saizen®, S20080036, 1.33 mg (4 IU), Laboratoires Serone S.A., Switzerland) from eukaryotic cells is reported and did not show any significant difference for the detection of doping with rhGH.
