Different laboratory tests are available for the control of alcohol abstinence or to monitor alcohol consumption. Traditionally blood alcohol concentration, liver enzymes (AST, ALT, GGT) and CDT (carbohydrate-deficient transferrin) have been used. Elevated values can provide evidence for alcohol consumption behaviour. Ethylglucuronide is a direct metabolite of alcohol (ethanol) and can be detected in blood, urine and hair.
The most suitable laboratory test for alcohol depends on the context (accident, control of abstinence, medical-psychological assessment, etc). As a forensic toxicological laboratory we perform all the above analyses.
