Testing for EtG Metabolite in Urine
In addition to EtG, recent scientific studies have identified ethyl sulfate (EtS) as a second specific metabolite or biomarker of ethanol. For this reason, we test and report EtS in conjunction with EtG, to confirm recent ethanol ingestion or exposure. The detection of EtG and EtS offers greater sensitivity and accuracy for determination of recent ethanol ingestion, than by detection of either biomarker alone.
We utilize the most sophisticated, sensitive, and specific equipment and technology available. After first screening for presumptive positives, we quantitatively confirm EtG/EtS by LC-MS/MS (liquid chromatography – tandem mass spectrometry). This combination of separate screening and confirmation methods provides highly accurate alcohol biomarker test results.
