Test Code YETGL Ethyl Glucuronide Screen, Urine

Clinical Information

This test is intended to screen for the presence of ethyl glucuronide in urine. Results are reported as 'presumptive positive' and are not confirmed. 

Synonym

  • ETG

Specimen Required

Preferred Container/Tube: Urine Container Cup
Acceptable Container/Tube: Urine Container Cup, Urine
Specimen Minimum Volume: 1 mL

Specimen Stability Information

Ambient: 24 hours
Refrigerated: 7 days

Rejected Due To

  • Quantity not sufficient
  • Urine Tubes with preservative

Reference Values

None Detected

 

Cutoff concentration by immunoassay detection:

500 ng/mL

Interpretation

Presumptive positive results may indicate the presence of ethyl glucuronide (EtG), a direct ethanol metabolite, in the urine sample. EtG can be detected up to several days even after complete elimination of alcohol from the body. Negative results may reflect the absence of EtG, or EtG present below the assay's limit of detection. Urine concentrations can vary extensively with fluid intake and other biological variables. 

Cautions

Urine samples should not include boric acid preservatives. Exposure to ethanol by other means such as hand sanitizers may cause a false positive result.
