How many drinks does it take to test positive for PEth?
For men, it appears that a daily consumption averaging ~2.5 standard drinks of alcohol a day (35 g/day) could produce a positive (>20 ng/mL) laboratory PEth finding. For women, a positive PEth (>0.20 ng/mL) might be produced by the consumption of 1.5–2 standard drinks (21–28 g/day) a day.

How can I lower my PEth levels?
Drinking experiments with heavy daily consumption have been associated with lower PEth levels than what we reported. In one study, binge consumption to 100 mg/dL daily for five consecutive days yielded PEth levels that range between 74ng/mL to 237 ng/mL between days 3 and 6 (Gnann et al., 2012).
How reliable is a PEth test?
How effective is PEth Testing? Because PEth is only formed in the presence of ethanol, it is a reliable test method for determining alcohol use. This also means that it has a high sensitivity due to its direct relation to alcohol consumption.
What can make a PEth test positive?
The authors suggest that “relevant amounts of hidden alcohol in nutrition or medication as well as inter-individual variations of enzyme activities for the formation of PEth might cause unexpected elevated concentration levels of PEth.” Even if the PEth test is 99% specific for alcoholic beverage consumption, that …
