Alcohol Biomarkers, Urine
Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.
This specimen was screened by immunoassay. Any positive result was confirmed by liquid chromatography with tandem mass spectrometry (LC/MS/MS).
The following threshold concentrations were used for this analysis:
Drug Screening Threshold Confirmation Threshold
Ethyl glucuronide 500 ng/mL 500 ng/mL
Ethyl sulfate 250 ng/mL
Alternative explanations should be explored for any positive finding.
This panel includes tests for specimen validity.
Please note that incidental exposure to alcohol may result in detectable levels of etg and/or ets. The Center for Substance abuse Prevention (CSAP) advises caution in interpretation and use of biomarkers alone to assess alcohol use. ETG/ETS results should be interpreted in the context of all available clinical and behavioral information.
