|Only available to the liver transplant team for service evaluation purposes. Send to lab immediately - sample must be frozen on date of collection to maintain sample integrity. Result interpretation: A positive result is highly suggestive of ethanol ingestion. False positive results may occur where yeast, glucose and bacteria contaminate the urine and the sample is stored incorrectly. False negatives may occur when bacteria contaminate the urine and the sample is stored incorrectly.
