Please note that Austin Pathology does not maintain chain-of-custody and thus results should not be used for legal purposes.


Ethyl Glucuronide is a metabolite of ethanol, and is a marker of alcohol ingestion. It may be detectable in urine for up to 80 hours after consumption of alcohol, however variation exists due to factors such as amount of alcohol consumed and indivudal metabolism.

False positive results may be seen from in-vitro production of alcohol and ETG from bacterial or fungal contamination of the urine.

False negative results may be seen with very dilute urines (creatinine <2 mmol/L).

All samples undergo a sample integrity check; in cases where the sample fails this check, testing will be deemed invalid and no result will be available.
