New 'state' markers for the detection of alcoholism.
Specific laboratory tests can be used to identify patients who are alcohol-dependent. The laboratory values of a number of biological 'markers', including carbohydrate-deficient transferrin, are often elevated in cases of chronic and acute alcohol abuse. Trait markers reflect a predisposition for alcoholism; state markers reflect actual alcohol consumption. It has been suggested that state markers can be subdivided into screening and relapse markers, and even further subdivided into pre-relapse markers, i.e. craving markers. We hypothesize that methanol metabolism and the presence of condensation products in the blood may serve as state and pre-relapse markers for alcoholism. Since the sensitivities and specificities of laboratory screening tests vary, and an absolute marker for alcoholism has yet to be identified, research in the area of biological markers for alcoholism should continue.
