What is a positive breath alcohol test?

A positive breath alcohol test indicates that a person is legally intoxicated or impaired. A positive determination is made once an individual’s blood alcohol concentration (BAC), which is the percentage of alcohol in your blood, reaches 0.08%. Once their BAC reaches that limit, it is illegal for that person to operate machineries such as a car, boat, or plane. While breath alcohol tests are predominately used by law enforcement, many employers also screen for alcohol abuse amongst employees using breath alcohol tests to ensure the ongoing safety and productivity in the workplace, often during pre-employment screenings or as a precautionary after a workplace accident has occurred.

Can you fail a breathalyzer without drinking?

There are instances where a person can fail a breath analyzer without drinking, in which there is a false-positive readout on the machine known commercially as a breathalyzer. One of the major causes of false-positive readouts on breathalyzer tests is a high acetone concentration in the breath. Breathalyzer machines often mistake acetone levels for alcohol levels. Acetone, a naturally occurring chemical used in nail polish remover, is produced when there is a high level of ketones in your blood, often present in individuals with hypoglycemia from conditions such as diabetes cardiac, kidney, or liver disease. Moreover, acetone can also be present in the breath of individuals who eat a low-carbohydrate diet, as such a diet focuses on increasing the level of ketones in your blood to promote fat burning.

Another cause of false-positive readouts on breathalyzer tests is a rare condition known as auto brewery syndrome, which is also referred to as gut fermentation syndrome and endogenous ethanol fermentation. When an individual has auto brewery syndrome, their body converts carbohydrates into alcohol, often making such individuals feel intoxicated without drinking any alcohol.

A breathalyzer can also deliver inaccurate results if it is not calibrated correctly or if the person taking the test consumed an alcohol drink less than 15 minutes before taking the test.

At Minor Emergency of Denton, we will take all of the above into account whenever we conduct a breath alcohol test.

How does a breath test work?

Practically speaking, when you take a breath alcohol test, you breathe into a tube that is connected to a breath analyzer machine which measures the amount of ethanol—the key ingredient in the alcohol we consume—present in your breath and then estimates your blood alcohol concentration based on how much ethanol the breath analyzer detects. After you breathe into the breath analyzer, a number will appear on the screen that shows your BAC.

The breath analyzer, or breathalyzer, can measure the amount of ethanol in your breath through negative and positive charged electrodes, known respectively as anodes and electrodes. When you breathe into the breathalyzer tube, the ethanol in your breath causes a reaction between the anode and electrode, which creates an electrical current that accurately corresponds to the ethanol concentration in your breath.
