ARUP lists the normal range as 'not established' with a detection limit that varies by instrument. Many labs use a practical reporting cutoff of about 10 mg/dL (0.1 g/L) and report anything lower as 'not detected'. Your lab may use a different cutoff.","sources":[{"title":"The enzymatic analysis of alcohol (ethanol) in serum and plasma with the alcohol dehydrogenase reagent: focus on intra-analytical and post-analytical aspects","url":"https://doi.org/10.11613/bm.2025.030501","publisher":"Biochemia Medica","year":2025},{"title":"Ethanol, Serum or Plasma - Medical (test 0090120)","url":"https://ltd.aruplab.com/Tests/Pub/0090120","publisher":"ARUP Laboratories"}]}],"review":{"status":"ai-verified","label":"AI-verified against cited sources.
