Dr. Bill 100, I need assistance interpreting the results of an ETG urine analysis. I took an ETG urine analysis and the results state: positive ethyl sulfate level 561.00; positive ethyl glucuronide level 1248. I am requesting assistance in understanding this data.
They tested for both metabolites EtG/EtS. These figures can only derive from the confirmation test and while above cutoff are nonetheless low.Quote:

As a comparison one 12 oz beer generated a peak urine level of 4,000 ng/ml in four hours and remained above 100 for 18 hrs. Dr. Skipper has a few examples here.Quote:

All of these figures are meaningless however as EtG is continually being eliminated and cannot be used to time drinking or extrapolate what, how much or time of consumption.
Notwithstanding a wealth of information to the contrary SAMHSA recently provided guidance on interpreting EtG test quantities noting any reading above 1000 as high and indicative of drinking.
