Reference Range
Alcohol Metabolites <500 ng/mL
Ethyl Glucuronide (ETG) <500
ng/mL
Ethyl Sulfate (ETS) <100
ng/mL
Clinical Significance
Ethyl glucuronide and ethyl sulfate are metabolites of ethanol (alcohol) that may be present in urine after ingestion of, or exposure to, drinks, foods, medication or other products containing ethyl alcohol. Incidental exposure to alcohol-containing products such as mouthwash or hand sanitizer have also been shown to produce positive alcohol metabolites test results. LC-MS/MS testing detects EtG and EtS regardless of the source. Therefore, we encourage you to interpret alcohol metabolite test results in light of the clinical picture.
