This test was developed and its analytical performance characteristics have been determined by Quest Diagnostics. It has not been cleared or approved by FDA. This assay has been validated pursuant to the CLIA regulations and is used for clinical purposes.

Performing Laboratory

Quest Diagnostics Nichols Institute
27027 Tourney Road
Valencia, CA 91355-5386

Reference Range(s)

Alcohol Metabolites <500 ng/mL
  Ethyl Glucuronide <500 ng/mL
  Ethyl Sulfate <100 ng/mL
Please note: These results are for medical treatment only. Analysis was performed as non-forensic testing.

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.
