How many drinks does it take to test positive for PEth?

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.

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 accurate is a PEth test?

In conclusion, new tests for monitoring alcohol or drug use, such as the blood PEth test, can be useful even though a low positive test (<112ng/ml) by itself may not be proof of relapse.
