Successful Strategies for the Analysis of EtG and EtS in Urine

A report from the National Highway Traffic Administration reveals that alcohol-impaired drivers are responsible for nearly one-third of all traffic-related fatalities. Impaired driving can lead to various penalties, often including court-mandated substance abuse evaluations, which may involve drug and alcohol urinalysis screenings..             

Ethyl glucuronide (EtG) and ethyl sulfate (EtS) are key biomarkers for detecting alcohol use. For the court system, these biomarkers offer significant benefits. A positive EtG result can indicate recent alcohol exposure, up to three days prior, even when ethanol is no longer detectable in the system. According to Restek, both EtG and EtS provide strong stability, analytical specificity, and a long detection window, making them reliable for monitoring alcohol use.  

With the Restek Raptor EtG/EtS LC column, Restek has provided fast, 4-minute, dilute-and-shoot LC-MS/MS method that supports high sample throughput. Save time and increase certainty with the definitive EtG/EtS method.
