Ethyl Glucuronide Screen
Label Mnemonic: ETHYLG
Epic Lab Code: LAB5744
Downtime Form: A-1a Miscellaneous Request
Commercial Mail-out Laboratory
5231 RCP
356-8593
Specimen(s):
Random Urine
Collection Medium:
Yellow top round bottom tube (no additive)
Minimum:
Preferred Minimum: 4 mL random urine Absolute Minimum: 1 mL random urine
Delivery Instructions:
Submit specimen to laboratory as soon as possible after collection.
Turn Around Time:
1-4 days upon receipt at reference laboratory. Confirmation testing may extend turn-around-time.
Reference Range:
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).
Comments:
Useful for general screening in 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 is preferred. Results do not accurately correlate with amount or frequency of ethanol use.
Methodology:
Qualitative Enzyme Immunoassay/Quantitative Liquid Chromatography- Tandem Mass Spectrometry
CPT Code:
80307; if reflexed add 80321
