Validation of an extended method for the detection of the misuse of endogenous steroids in sports, including new hydroxylated metabolites.
Endogenous steroids are amongst the most misused doping agents in sports. Their presence poses a major challenge for doping control laboratories. Current threshold levels do not allow for the detection of all endogenous steroid misuse due to great interindividual variations in urinary steroid concentrations. A method has been developed and validated to screen for traditionally monitored endogenous steroids in doping control as well as specific hydroxylated/oxygenated metabolites in order to enhance the detection capabilities for the misuse of endogenous steroids.
