What are the benefits of EtG over traditional urine alcohol testing?
EtG testing offers a longer time period for detection after the consumption of ethyl alcohol, as compared to direct testing for ethyl alcohol in urine. Based on the current body of knowledge, the presence of EtG is a specific indicator of ethyl alcohol (ethanol) exposure. Due to specimen collection and storage factors, fermentation in a urine sample may lead to false positives for ethanol since glucose and yeast may be present in the urine. Since EtG is created during the metabolism of ethanol, there is no currently known means for a positive EtG result to arise due to EtG formation in the collected sample.
