Qualitative screening in doping control by MALDI-TOF/TOF mass spectrometry: A proof-of-evidence

The analysis of doping agents in biological fluids is of top significance in clinical and forensic toxicology. Herein we describe the study of a screening method for the detection of a mixture of drugs of potential abuse including cocaine and its metabolites. By using matrix-assisted laser desorption/ionization MALDI-TOF/TOF mass spectrometry. This screening procedure to detect the presence of different drugs, avoiding time consuming procedures could be useful in different fields of forensic analytical toxicology, including antidoping analysis.
