A downscaled multi-residue strategy for detection of anabolic steroids in bovine urine using gas chromatography tandem mass spectrometry (GC-MS3)

A higher GC-MS technique's specificity was achieved by detecting the steroids using GC-MS3. Nevertheless, it was decided to screen routinely sampled urine with GC-MS2 whereas GC-MS3 was applied to confirm the presence of anabolic steroid residues in suspected sample extracts.
