| Method: ||Enzyme Immunoassay|
|Note: ||Ordering Recommendation: |
Initial test to identify recent ethanol exposure (within 1 - 4 days after ingestion).
Ethyl glucuronide is a direct metabolite of ethanol and can be detected up to 80 hours in urine after ethanol ingestion. The cutoff for positive by immunoassay is set at 500 ng/mL. A positive result will be confirmed by liquid chromatography tandem mass spectrometry (LC-MS/MS).
