Analysis of 19-Norsteroids, testosterone and precursors metabolites in human urine by CG/C/IRMS
Project Title: Analysis of 19-Norsteroids, testosterone and precursors metabolites in human urine by CG/C/IRMS
Researchers: C. Ayotte (Institut Armand-Frapier (INRS), Québec, Canada), W. Schänzer (Deutsche Sporthochschule, Köln Insitut für Biochemie, Köln, Germany), M. Ueki (Tokyo Antidoping Laboratory, Japan)
Year accepted: 2002
Summary: This project is aimed at applying the IRMS (isotope ratio mass spectrometry) to the detection of the “natural” testosterone and 19-nortestosterone anabolic agents. Complement of the existing GC/MS methods, the GCIC/IRMS permits the differentiation of the exogenous or endogenous origin of urinary androgens metabolites, by measuring the isotopic content of their carbon atoms.
