Ethyl Glucuronide Screen with Reflex to Confirmation, Urine
Also known as: ETG SCR
Use
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 is preferred. Results do not accurately correlate with amount or frequency of ethanol use.
Special Instructions
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.
Limitations
The presence of Ethyl Glucuronide (EtG) in urine is not a unique marker of ethanol ingestion. False positive results can occur from microbial formation or fermentation, and false negative results can occur from bacterial degradation.
