| Description | Etiocholanediol is one of the compounds tested to allow for the unequivocal identification of the presence of urinary anabolic steroids and metabolites banned for use in sport by athletes. In urine samples collected for anti-doping purposes with moderately elevated testosterone and epitestosterone ratio, or when a suspicion of manipulation of the sample occurs, Etiocholanediol is tested for further clarification. It is worth mentioning that the concentration parameters vary enormously according to the gender of the subjects, ethnic origin, the urine collection period (before or after effort, period of the day) and the hydration state of the athlete. Urinary steroid data using several methodologies are not appropriate for identification purposes and to an extent not unique to individuals. (PMID: 16337352 , 16338181 , 16337352 , 17260133 ). |
