Factors that can impact the accuracy of a Breathalyzer

| Jun 15, 2017 | blog, Firm News

An operating a vehicle under the influence charge and conviction can impact many areas of your life, potentially affecting you financially, professionally and personally. If you live in Ohio, are over 21, and demonstrate a blood-alcohol content of 0.08 percent or higher, or if you are under 18 and demonstrate a blood-alcohol content of 0.02 percent or higher, you may face a charge.

The device used to assess your level of impairment is a Breathalyzer, and while these tools are often accurate, they are not fool-proof, and they must undergo regular testing and calibration in order for their results to be valid. There are a number of factors that have the capacity to impact the overall accuracy of a Breathalyzer reading, however, and these factors include:


If you suffer from diabetes and your breath test shows that you are drunk, this may be due to your health condition. If your body is producing significant ketones, as is the case for some who suffer from diabetes, this has the capacity to produce a false Breathalyzer reading.

Certain bodily fluids

If you have blood or vomit in your mouth when you undergo your breath test, this, too, may produce an inaccurate result. Even burping can render the results inaccurate.

Electrical interference

Another element that may lead you to produce an inaccurate breath test reading is the presence of electronic interference. Radio waves, cellphone towers and even law enforcement radios can affect the results of your breath test.

Tobacco and smoke

The presence of tobacco or smoke in your mouth also makes this list. Most authorities are aware of this, and they know to watch you closely after pulling you over to make sure you do not smoke before they give you the breath test.

Because the repercussions associated with an OVI can be so severe, it is critical that the results of your breath test are unquestionable.
