I had 3 beers on Sunday, and was surprised by an ETG test on Tues. 4:40 pm. What are my chances of passing with 44 hrs. since having the beers?

EtG is highly sensitive... too sensitive, often picking up incidental alcohol exposure.

Nonetheless published research has established that detection falls within a wide range. 30-110 hours with an average of 66 hr.

To overcome the problem of hypersensitivity the recommended test threshold is 500 ng/ml although EtG is currently unregulated.

Thanks for your help/knowledge!

Pleased to help

An October 2009 study lists the “Urinary detection times for EtG and EtS after different doses of alcohol” - Go to p. 59 of the study for this information at the link below. NOTE: Alcohol dose is based on Grams per Kilogram of body weight (g/kg) not BAC level. Of further note is the small number of test subjects in each study (see N in the Table) and the variance in the results.

If you require clarification please post and I will get back to you.
