  7. 5. Liquid chromatography : mass spectrometry study of two biochemical alcohol markers

    Författare :Niclas Nikolai Stephanson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The interest in biochemical alcohol markers for detecting acute and chronic alcohol consumption has expanded greatly during recent years. The development and application of laboratory tests identifying early problematic drinking and monitoring abstinence have the potential of reducing the healthcare costs and suffering associated with alcohol misuse.
