Specimen(s):
Random Urine
Collection Medium:
) |
| Yellow top round bottom tube (no additive) |
Minimum:
Preferred Minimum: 4 mL random urine Absolute Minimum: 1 mL random urine
Delivery Instructions:
Submit specimen to laboratory as soon as possible after collection.Turn Around
Time:
1-4 days upon receipt at reference laboratory. Confirmation testing
may extend turn-around-time.
Reference Range:
Screen cutoff concentration: 500 ng/mL
Interpretive Data:
Ethyl glucuronide is a direct metabolite of ethanol and can be
detected up to 80 hours in urine after ethanol ingestion. The cutoff
for positive by immunoassay is set at 500 ng/mL. A positive result
will be confirmed by liquid chromatography tandem mass spectrometry
(LC-MS/MS).
Comments:
Useful for general screening in contexts of compliance and/or abuse. A
screen with reflex testing is the preferred method for ruling out
ethanol exposure. For follow-up testing of a presumptive result, Ethyl
Glucuronide and Ethyl Sulfate, Urine, Quantitative is preferred.
Results do not accurately correlate with amount or frequency of
ethanol use.
Methodology:
Qualitative Enzyme Immunoassay/Quantitative Liquid Chromatography-
Tandem Mass Spectrometry
