This test first screens urine for ethyl glucuronide (EtG) and ethyl sulfate (EtS), metabolites that indicate recent alcohol consumption. Positive screens are automatically confirmed with definitive testing methods (such as LC-MS/MS), ensuring accurate results for clinical, workplace, and legal applications.
This test is used in addiction treatment programs that require documented abstinence, workplace drug testing, legal proceedings, and other settings where reliable, defensible alcohol testing is needed. Detection windows of 3-5 days are longer than for direct alcohol measurement. Sample type is urine, often under chain-of-custody protocols.
We are CLIA certified, the highest level of Medical industry compliance and standards.
