A Single‐Aliquot Strategy for Simultaneous Carbon Isotope Confirmation of 6‐Oxo‐Androstenedione and Testosterone Misuse in Doping Control

open access: yesDrug Testing and Analysis, EarlyView.
This method enables simultaneous carbon isotope confirmation of 6‐oxo‐androstenedione and testosterone markers from a single urine aliquot, using bench‐top extraction, two preparative HPLC steps with intermediate acetylation, and GC/C/IRMS analysis. It was fully validated according to WADA requirements, and real samples demonstrated its fitness for ...
