Ethyl Glucuronide and Ethyl Sulfate, Urine, Quantitative
Copy Utility
May be useful in the assessment of ethanol exposure in the contexts of compliance and/or abuse. For general screening, Ethyl Glucuronide Screen with Reflex to Quantitation, Urine (2007912) is preferred. Results do not accurately correlate with amount or frequency of ethanol use.

Ethyl glucuronide (EtG) and Ethyl Sulfate (EtS) are direct metabolites of ethanol. EtG and EtS can be detected up to 80 hours in urine after ethanol ingestion and the presence of both metabolites can be used as markers for recent alcohol use. The presence of EtG, alone in urine, is not a unique marker of ethanol ingestion. False positive EtG results can occur from microbial formation or from fermentation and false negative EtG results can occur from bacterial degradation. The analytical measurement range is 100-10,000 ng/mL.
Compliance Statement B: For laboratory developed tests not using a RUO kit, and for FDA approved, cleared or 510(k) exempt assays with alterations. This test was developed and its performance characteristics determined by ARUP Laboratories. The U. S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions.
