Resolved Question:

Would low blood glucose cause me to read very high on an alcohol breath test? I had had one pint of shandy several hours before and the test showed that I had 72mg of alcohol in my breath.
At the roadside I was normal apart from very low blood glucose 3.2mmol
I had NOT been drinking other than that and can not understand it.

Hello and thank you for writing to JustAnswer Health with your concern.

A very high blood glucose can cause an inaccurately high reading on an alcohol breath test, not a low blood glucose.

If you had little in your stomach when you drank the alcohol that will lead to a higher alcohol level sometimes, rather than if you had had it with a full meal.

Hi Susan

About an hour before I was tested I had really bad hiccps and drank a shot of vinegar to see if that would help. It just made me very sick!

I can't understand any reason for the high reading, the equivilent of 1/2 pint of beer should not do that. I weigh 9 stone and had been awake for 20 hours at that point.

Any pointers would be very helpful..

This article is factual about breathalysers, and may help you to understand your reading.

From what I have read, the modern Breathalyzer's should not be fooled by vinegar, but the older models could give a misreading related to vinegar. So to determine if this had anything to do with your reading would take research into the type of breathalyser that was used, and such - you would probably need an attorney if you were going to try to check out this type of information to build a case.
