No one can predict except in very broad time spans if any given individual will pass or fail an EtG test.

A "bottle of wine" (approx 5 standard drinks) would usually bring your BAC to about .08 requiring about 5 hours to BAC=0, leaving 33 hours for EtG elimination.

Using those figures there is a study that closely corresponds (9 people dosed to .08) and the average clearance time for EtG was 32 hours. (Moore, 2010, O-2).

It is my opinion that you would still be positive but it could depend on the cutoff of the test, 100 v 500 ng. Either way you are on the cusp.

I have no confidence in the validity of EtG testing but the results continue to surprise me by the false negatives returned after even significant drinking episodes.

Please advise when you get the results.

You should be nervous.

They don't need much urine and would have required you to remain until the sample provided was sufficient.

Please let us know the results. This intrigues me.

You don't happen to know the cutoff of the test, do you? Also, if you don't mind would like to know your gender, age, and weight.

Would you like to do a little further calculating? If so tell me how long it took to drink the bottle of wine. That is when you started drinking and when you ended.

What were you told about this test? Usually, clients are advised that even small amounts of alcohol can be detected for upto 5 days.

Here's the problem. A bottle of wine contains a specific amount of alcohol that can be reduced to standard drinks. A glass of wine is subjective. 5 oz of wine (10% abv) is one standard drink. One standard drink contains 13.7 grams of pure alcohol. A bottle contains 25 fl. oz..

Now, basically you consumed the wine across a 7 hour period? That is of some importance because EtG is created as alcohol is metabolized and begins eliminating about 4-5 hours after the first drink. You metabolize alcohol at a fixed-rate limited amount. Those calculations are important to making an estimate....guess is more accurate.

First, I need to calculate your BAC just so I have a start point.
