A method for separation and quantitation of carbohydrate deficient transferrin (CDT) in order to decide a person's alcohol consumption during the most recent time. Lipoproteins are precipitated in blood serum, saturated with iron, and then the sample is centrifuged after a short storage period. The supernatant of the centrifuged mixture is then diluted with water. Subsequently the mixture is injected to an ion exchange column, when a saltgradient is used for separation of the isoforms of transferrin. A chromatogram is developed by means of HPLC and a filter for absorbance at 460 nm. Should the chromatographic profile show increased values of CDT (*,**), more than 0.8 % of total transferrin, it is a highly specific marker for heavy alcohol consumption.

Procédé de séparation et de quantification de transferrine pauvre en hydrate de carbone (CDT), permettant de déterminer la consommation d'alcool récente d'une personne. Des lipoprotéines sont précipitées dans du sérum sanguin et saturées avec du fer, après quoi l'échantillon est centrifugé après une courte période de stockage. La substance surnageante du mélange centrifugé est ensuite diluée avec de l'eau. Le mélange est ensuite injecté dans une colonne d'échange d'ions, et un gradient salin est utilisé pour la séparation des isoformes de transferrine. Un chromatogramme est développé par chromatographie liquide haute performance (HPLC) et un filtre permettant l'absorbance à 460 nm. Si le profil chromatographique indique des valeurs accrues de CDT (*, **), notamment une valeur dépassant 0,8 % de transférrine totale, il agit comme un indicateur à spécificité élevée d'une forte consommation d'alcool.
