PEth has a potential in abstinence monitoring, since PEth could be detected for up to 12 days after a single drinking event.
Will one drink show on PEth test?
A single bout of alcohol drinking will not produce detectable amounts of PEth; this would require continuous drinking of approximately 1000 g of alcohol over about 2 weeks. The sensitivity of PEth for the screening of alcohol use is greater than for traditional biomarkers.
Because it has been found in limited lab-based trials to require a significant amount of ethanol, >100g (about 7 standard drinks), to trigger a positive PEth test, with the typical cutoff of 20ng/ml, it has been suggested that a positive test can be considered proof of alcoholic beverage consumption.
