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.
Qualitative Enzyme Immunoassay/Quantitative Liquid Chromatography-Tandem Mass Spectrometry
Transfer 4 mL urine with no additives or preservatives to an ARUP Standard Transport Tube. (Min: 1 mL)
Ambient: 20 days; Refrigerated: 20 days; Frozen: 20 days
Screen cutoff concentration: 500 ng/mL
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).
If the specimen screens positive, then Confirmation/Quantitation by LC-MS/MS (ARUP test code 2007909) will be added to confirm result. Additional charges apply.
80307; if reflexed, add 80321 (Reflexed Alt Code: G0480 )
