This is a reporting cutoff, not a range from healthy people: EtG is normally absent unless alcohol was consumed or came from another source. Screening immunoassays and test strips often use 500 ng/mL (ARUP's screen cutoff), and a treatment or monitoring program may set its own cutoff. Use the cutoff printed on your report.","sources":[{"title":"Ethyl Glucuronide and Ethyl Sulfate, Urine, Quantitative (test 2007909)","url":"https://ltd.aruplab.com/Tests/Pub/2007909","publisher":"ARUP Laboratories"},{"title":"Ethyl Glucuronide Screen with Reflex to Confirmation, Urine (test 2007912)","url":"https://ltd.aruplab.com/Tests/Pub/2007912","publisher":"ARUP Laboratories"},{"title":"Sensitivity and specificity of a commercial urinary ethyl glucuronide (ETG) test in heavy drinkers","url":"https://doi.org/10.1016/j.abrep.2020.100249","publisher":"Addictive Behaviors Reports","year":2020}]}],"review":{"status":"ai-verified","label":"AI-verified against cited sources.
