This paper describes the use of the biological markers glutamyltranspeptidase (GGT) and carbohydrate deficinet transferrin (CDT) to assess the frequency of heavy users of alcohol in the general traffic flow. CDT is a relatively new method and was used to provide a more precise assessment. Random breath tests were carried out at the roadside and drivers with a positive blood alchol content asked to provide a blood sample. Serum GGT was determined using established clinical methods. Serum CDT was determined using a commercially available kit. The results were compared to the results of earlier investigations which suggested that about 40% of alcohol positive drivers had elevated GGT values. The results confirmed that about 40% of alcohol positive drivers could be considered as problem drinkers.
