Thank you for your query.
Not likely. Hand sanitizer(s), mosquito repellent, gel deodorant, mousse, chewing gum, painting solvents and aftershave -- all can contain alcohol, but the level and topical absorption is very less. If there was a significant absorption, you would have felt intoxicated! This could be false positive result. This is especially true if just urine ethanol levels are measures. Alcohol can form in the urine if there are bacteria or fungi. I recommend you to go for a retest and use newer modalities of alcohol analysis like ethyl glucuronide (EtG).
Hope this helps
