Thanks for using the forum.
It is possible for the urine test for alcohol to give a false positive. If they are testing for EtG, the use of other household products such as hand sanitizer, or mouthwash that contain alcohol can cause a positive result. In these cases the alcohol is absorbed through the skin or oral mucosa.
Additionally, diabetics can get a false positive result if the urine sugar level is elevated and yeast is present in the urine. The yeast can ferment the sugar into alcohol if the test is allowed to sit for a while before it is tested.
I hope this helps.

This is anecdotal BUT ive heard of diabetics failing breath tests. Id call the maker of the test and see if high ketone's can cause a false positive. being diabetic with pore control you might have high ketone or sugar in your pee
