3 Ways a Breathalyzer Test Can Be Wrong

In a DUI case, the results of a breath test is one of the most common pieces of evidence prosecutors rely on. However, these tests are highly flawed, and there are a number of small variables that can completely invalidate the results. If you’ve been arrested for driving under the influence, call our experienced Los Angeles DUI attorneys today for tough defense.

Your Diet & Hygiene

Believe it or not, both good hygiene and a healthy diet could lead to a DUI arrest. Many mouthwashes contain ethanol, which is the same type of alcohol found in alcoholic beverages. If you’re stopped by a police officer after using mouthwash, it’s very possible to blow a false positive on a breathalyzer test.

Many people follow a low-carb or carbohydrate-free diet these days, and these diets can also lead to a false positive. When you have a very low carbohydrate intake, your body responds by going into a state of ketosis. This essentially means that your body will rely on fat for energy, rather than sugars. However, the ketones that are produced by your body in this state can actually cause a false positive on a breath BAC test.

Calibration/Administration of the Test

Breathalyzers are very temperamental devices, and must be calibrated regularly to ensure that they are working properly. If a device was not properly calibrated at the time of your test, the results will generally be dismissed as evidence against you.

The way the test is administered plays a big role, too. Factors such as the time the officer waited before administering the test, as well as whether or not they watched you for the entire waiting period, can all call the results of these tests into question.

Health Conditions or Medication

One of the most common health conditions which can impact the results of a DUI test is acid reflux, or gastroesophageal reflux disease. If you suffer from this condition, your stomach will regurgitate stomach acids back up into the esophagus, often causing heartburn. Other gasses and vapor come up with the acid, and can cause large inaccuracies in the results of a breathalyzer test.
