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.
Qualitative Enzyme Immuonassay
Transfer 4 mL urine with no additives or preservatives to an ARUP Standard Transport Tube. (Min. 1 mL)
Ambient: 20 days; Refrigerated: 20 days; Frozen: 20 days
Screen cutoff concentration: 500 ng/mL
Screening results are obtained by immunoassay. Results obtained by immunoassay are not confirmed unless confirmation testing is specifically requested.
Ethyl glucuronide is a direct metabolite of ethanol and can be detected in urine up to 80 hours after ethanol ingestion. This immunoassay cutoff for positive is set at 500 ng/mL.
Compliance Statement B: For laboratory developed tests not using a RUO kit, and for FDA approved, cleared or 510(k) exempt assays with alterations. This test was developed and its performance characteristics determined by ARUP Laboratories. The U. S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions.
