Medical Conditions Affecting Breath Test Results

Medical Conditions Can Impact Blood and Breath Testing in San Diego DUI Cases

Breath testing for alcohol can be inaccurate due to a significant number of common medical conditions. These common medical conditions include asthma, diabetes, flu/fever, chronic obstructive pulmonary disease (COPD), chronic bronchitis, emphysema, and gastro-esophageal reflux disease (GERD), among others. These common medical conditions can lead to a breath test result indicating a blood-alcohol content above .08, when this was not the case.

Inaccurate Breath Test Results

In order to obtaining an adequate sample of deep lung air, breath testing machines require an air flow for five continuous seconds, or longer. Not surprisingly, everyone's ability to blow into a breath test device for a continuous period of time will be different and can be affected by asthma, chronic bronchitis, emphysema and heart disease.

Chemical Substances in the Breath

A major problem with breath testing, even for healthy individuals, is that it is possible for breath testing devices to misread naturally occurring substances in the breath as alcohol (such as acetone). People who suffer from diabetes can produce more of these chemicals that can be read as alcohol. When we are splitting hairs to arrive at a BAC of .08, one can see how important this misreading can be.
