[Evaluation of an increased blood level of GGT, CDT, methanol, acetone and isopropanol in alcohol intoxicated automobile drivers. Alcoholism indicators instead of medical-psychological examination].

Several thousand blood samples were taken from alcoholized drivers at the Blood Alcohol Examination Centre of the Institute of legal Medicine at Cologne University. These samples showed blood alcohol contents (BAC) as well as GGT, CDT, methanol, acetone and isopropanol levels which indicated alcohol addiction. The blood samples were selected by the drivers' ages and their BAC, but in some cases the GGT also played a role.
