Dr. Bill,

I had my last drink at 11:30 this past Monday evening. I'm going in for an ETG test on Monday November 7. Will there be any ETG left in my system at that time? And to my knowledge, am I correct in saying that EtG does not accumulate it continues to eliminate?

EtG is not cumulative (ex: Sarkola 2003). It follows much the same elimination profile as ethanol but slower. A graph is available here (see Figure 4, p. 597)

Regardless of amount consumed you will be clear of EtG at the time interval noted.

I know that there is no so called safe zone when talking about an EtG test because of the inhaling of certain substances can have a reading of EtG over 100. What I want to ask is strictly related to alcohol consumption. Is there any one on record that has failed an ETG because of consuming the beverage an alcohol one week after consumption? Just taking the inhaling of other things out of the question for this time being,

To the best of my knowledge* there is no study (published or not) where alcohol consumption has resulted in detectable EtG past 140 hours (one case at that level). That time is a singular instance and unexplained. 80 hours is exceptional although appears in some studies; therefore the qualifier "up to".

*I currently index 255 studies on EtG/EtS. About 30 of those studies deal with elimination. Most of the elimination studies have been conducted on small unrepresentative groups. Usually in a laboratory, detox or psychiatric setting.
