3 ways that Breathalyzer tests can give inaccurate results

On Behalf of | Nov 5, 2021 | DUI charges

In driving under the influence (DUI) cases, Breathalyzer tests will often form a key part of the evidence. While chemical breath tests are widely considered to be among the most accurate ways to measure blood alcohol content (BAC), the technology is not infallible. 

A conviction for a DUI offense can have life-altering consequences on those involved. As a result, it is important to consider how Breathalyzer tests could be wrong. Outlined below are three ways that Breathalyzer tests can give inaccurate results. 

Interference from electronic devices

Research suggests that interference from electronic devices can skew the results of a Breathalyzer test. Radio frequency transmissions from police radios could emit electromagnetic interference, leading to untrustworthy readings from chemical tests. 

Poorly calibrated equipment 

For Breathalyzer equipment to be effective, officers are required to adhere to guidelines regarding calibration. Equipment that has been poorly maintained or improperly calibrated could result in inaccurate readings. Additionally, law enforcement is expected to be trained in the use of Breathalyzer tests and follow protocol regarding their application. 

Specific health conditions 

Certain health conditions could impact the results of a chemical test. For example, gastroesophageal reflux disease (GERD) can result in undigested alcohol being forced back into the digestive tract. As a result, there may be a higher concentration of alcohol present when the individual takes the test. 

It is important to note that technology is not always correct. There are numerous ways that errors may occur, and these errors can result in charges being defended in court. 

Understanding the workings of chemical breath tests could be in your best interests. If you find yourself facing DUI charges, then there are legal options available to you.
