Summary
This study aims to determine the effectiveness (sensitivity and specificity) of individual serum and urine steroid, hematological and peptide hormone profiles within the Athletes Biological Passport to detect testosterone micro-dosing in men, and determine the applicability of venous and capillary blood analysis as complimentary testing procedures to those stated for the Athletes Biological Passport. Furthermore, the data for individuals would be collated and evaluated to include legal planning and expert opinion as to how a case against a potentially doping athlete could be undertaken and what data would be required. This information would enable WADA laboratories to identify future testing requirements of samples to ensure all applicable data is available for the Athletes Biological Passport.
