CPT Code is subject to a Medicare Limited Coverage Policy and may require a signed ABN when ordering.
Clinical Significance
Drug Toxicology Monitoring Alcohol Metabolites, with Confirmation, Urine - 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.
