Can a DUI Test Result
in a False Positive?
March 2, 2022
On suspicion of driving while under the influence, a police officer may stop your vehicle and request that you take a roadside Breathalyzer test. Unfortunately, Breathalyzer tests are not always accurate when measuring a driver's blood alcohol concentration (BAC). Due to some underlying circumstances, a Breathalyzer test may give a false positive.

False Positives for DUI Tests
Breathalyzer tests, also known as blood alcohol tests, are used by police officers on individuals suspected of drunk driving to measure the level of alcohol in their blood. However, just like all other machines, Breathalyzers are not perfect, and the tests aren’t always accurate.
On certain occasions, the Breathalyzer test may give a positive result even when you weren't drinking alcohol. Unfortunately, this may result in a DUI arrest or charge. However, that doesn't mean you should accept the false-positive test result without a fight. An experienced DUI/DWI attorney can help contest the validity of the Breathalyzer test result, dispute the allegations, and attempt to establish your innocence.
Possible Reasons for a False Positive
Here are some reasons why a Breathalyzer test may issue a false-positive result even when you weren't drinking:
Calibration of Equipment: For the Breathalyzer to function properly, the device must be properly calibrated. If the police officer fails to calibrate the Breathalyzer appropriately, it may issue a false-positive test result.
Medical Conditions: Gastrointestinal medical conditions, including acid reflux or heartburn, may also result in false-positive readings. If you have any of these medical conditions, you may have valid grounds to contest the test results.
Medication: Certain medications and drug prescriptions, including cold medications, antidepressants, and quinolone antibiotics, can increase the possibility of false-positive results on Breathalyzer tests. If you take any of these medications before driving, it may lead to a positive result for the DUI test.
Mouth Contaminates: Having acid in your mouth, esophagus, or stomach may cause your BAC levels to increase, thereby causing a false-positive test reading.
Food/Drinks: Some non-alcoholic or fermented food and drinks may enable the Breathalyzer test to give false-positive readings. For example, ripe fruits, protein bars, pecans, and energy drinks may destabilize your BAC or mess with the Breathalyzer test.
If you or someone you know is facing DUI charges due to a false-positive test result, you need to reach out to a skilled criminal defense attorney immediately. Your lawyer can investigate the reasons for the Breathalyzer false positive and strategize an effective defense to fight your charges and help you avoid the devastating legal consequences of a criminal conviction.
