Useful for general screening in contexts of compliance and/or abuse. For follow-up testing of a presumptive result, confirmatory testing by mass spectrometry is available. For automatic reflex testing on all presumptive positives, Ethyl Glucuronide Screen with Reflex to Quantitation, Urine (2007912) is recommended. Results do not accurately correlate with amount or frequency of ethanol use.
