Etg tests are sensitive to alcohol metabolites as you have mentioned. It would be interesting to know how many ng's you all tested for. Anything under 500 ng's could/should be considered incidental exposure. Anything OVER 500 is definite alcohol consumption.
That's not to say that anything under 500 is not alcohol consumption, just that it is too low to be positive that alcohol was consumed. Low levels could also indicate incidental abuse (ex: drinking high doses of cough syrup, vanilla extract, mouthwash, etc).
