Can a person’s breath be used to determine their blood alcohol level? Some people say no. The police officers who administer the breathalyzer use the machine to determine your blood alcohol level by evaluating the amount of alcohol in your breath.

When you drink alcohol, it is not immediately digested; a portion of it passes through your lungs. Some alcohol you consume passes through your lungs’ membranes and into the air. As a result, the air in your lungs captures a small portion of the alcohol in your body.

Challenging a Breathalyzer Test

A variety of factors influence a breathalyzer’s accuracy. Some are based on assumptions, while others are based on science. It should be your own unique perception that is tested to determine your blood alcohol content.

Refusing a Breathalyzer Test

If you refuse a breath test, a report of refusal form is sent to the Secretary of State. You will have only fourteen days from the date of your alleged refusal to contest the allegation. In the event of a refusal, you must fight it every step of the way.

DUI Driving Patterns

It is critical to investigate and challenge the reason an officer stopped you. This will provide you with numerous legal opportunities in court.


Many people develop opinions about your case before the officer pulls you over. Unsafe driving or speeding may have prompted the officer to suspect something in the first place. This bias may be utilized by a good defense attorney to show that the officer was predisposed to arrest you.

What Happens During a Breathalyzer Test?

Your healthcare provider will teach you to inhale deeply and exhale into a bag-like container. Then you will be asked to drink something. The gasses in your breath will be evaluated again 15 to 30 minutes after you drink the liquid.

For the next 3 to 5 hours, samples of your breath will be taken every 15 to 60 minutes. During the test, do not sleep, smoke, or exercise. This may have an impact on your test results.

Care Agreement

Plan your care routine.  Learn about your medical condition and how it can be treated. Consider treatment options with your healthcare providers to determine the type of care you want. You always have the option to refuse treatment.

The Bottom Line

Before your breath test, it is critical that you consume only the prescribed prep diet. Too much of either gas can cause issues like diarrhea or stomach pain. Breath tests aid in the identification and diagnosis of abnormal levels of these gasses.

DHC will measure your regular hydrogen and methane levels without interference from certain foods to accurately diagnose the source of your digestive problems. Certain foods and beverages significantly impact your hydrogen and methane levels, which can skew your breath test results.
