Usefulness of carbohydrate-deficient transferrin in alcohol-elated problems

BACKGROUND: Carbohydrate-Deficient Transferrin (CDT) is a new marker for excessive alcohol drinking. It appears to be useful to detect alcoholism, harmful consumption and relapse. It have been introduced in our country recently. METHOD: Recent studies about utility of CDT have been reviewed. RESULTS: Sensitivity and specificity of CDT level as a marker of alcoholism were 72-97% and 31-81% respectively. As a marker of harmful consumption its sensitivity was 15-69% and its sensitivity was higher than 82%. CDT was demonstrated to be a effective maker for evaluating alcoholic abstinence in alcoholic patients. CONCLUSIONS: CDT determinations have a high specificity for screening heavy drinking in different settings. Problems related to its sensitivity are discussed.
