Ethyl Glucuronide Screen with Reflex to Confirmation, Urine
Copy Utility
Ordering Recommendation
Useful for general screening in the assessment of ethanol exposure in the contexts of compliance and/or abuse. A screen with reflex testing is the preferred method for ruling out ethanol exposure. For follow-up testing of a presumptive result, Ethyl Glucuronide and Ethyl Sulfate, Urine, Quantitative (2007909) is preferred. Results do not accurately correlate with amount or frequency of ethanol use.

Specimen Required
Random urine.
Transfer 4 mL urine with no additives or preservatives to an ARUP Standard Transport Tube. (Min: 1 mL)
Refrigerated.
Ambient: 1 week; Refrigerated: 1 month; Frozen: 1 month
Reference Interval
Screen cutoff concentration: 500 ng/mL
Interpretive Data
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).
