The proposed method, set\u2010up, and validated to detect the abuse of dextran, hydroxyethyl starch and mannitol as a doping practice in sport, involves only one enzymatic hydrolysis step and the direct injection into a liquid chromatography\u2010tandem mass spectrometry (LC\u2010MS\/MS) system.<\/jats:p><jats:p>The chromatographic conditions were optimized to allow the efficient separation of compounds with the same molecular weight. Good linearity (R<jats:sup>2<\/jats:sup> 0.990\u20130.995) and reproducibility of relative retention times (CV% lower than 1) and of relative abundances of characteristic ion transitions (CV% lower than 10) were obtained. The lower limits of detection and quantification were in the range of 30\u2013100\u2009\u00b5g\/ml.<\/jats:p><jats:p>Since the analytes studied are present also in non\u2010doping products (e.g. in fruit as well as in food products and drugs additives), the developed method was also used to establish a range of reference urinary concentrations: 600 doping control samples and 30 samples from volunteers not using any medication were considered. While the hydrolysis products (isomaltose and maltose hydroxyl\u2010ethylated), used as specific markers for the detection of dextran and hydroxyethyl starch abuse, were not detected in urine; mannitol was present in all urines in a concentration range of 30\u20131200\u2009\u00b5g\/ml. Since no criteria of positivity for mannitol has been established yet, the results obtained in this study could be considered, in combination with those of previous researches, as a starting point to fix a threshold value for doping control purpose.
