More Information on Breathalyzer and Blood Tests Used in DWI Cases
If a driver is found to have a blood alcohol concentration (BAC) of 0.08% or higher, they can be arrested and charged with DWI, as stated by the Texas Department of Transportation. Breathalyzer tests are commonly used in this regard because they give a quick reading; however, the results may not always be accurate, according to data from MedlinePlus. Alternatively, blood testing may be used to verify BAC. Blood samples are generally deemed more accurate than breathalyzer tests, but they are generally unable to be performed on site by an officer.
If you have been arrested because of a failed breathalyzer or blood test, working with a lawyer who has a focus in this area of the law may be helpful in developing a defense strategy in an effort to secure a better outcome for your case.
Potential Causes of a Failed Breathalyzer or Blood Test
Breathalyzer tests can be used to determine BAC; however, various factors can affect the accuracy of a reading. Because these tests are designed using technology that reads the microscopic levels of alcohol that may be present in one’s breath and lungs using infrared light, it is not an exact science. Here are some common factors that may affect the reading of BAC with a breathalyzer test:
- One’s blood chemistry
- How forcefully one blows onto the reader
- The air temperature
- Certain medications
- Diabetes (if one has low glucose in their blood, the symptoms may seem very similar to drunkenness. Furthermore, acetone on the breath due to the low glucose may get read erroneously as positive for alcohol on a breathalyzer.)
- Ketosis (high-protein diets can cause high acetone levels in the lungs, resulting in a false positive on a breathalyzer)
- The use of certain mouthwashes or breath sprays (they may have concentrations of alcohol, which may cause remnants of alcohol on the breath for as long as 20 minutes after use)
How a Lawyer May Be Able to Dispute a Breathalyzer or Blood Test in Your Defense
If you believe your breathalyzer or blood test was inaccurate due to one of the above-mentioned factors, or perhaps another reason, you may want to consider discussing your situation with a legal professional. A Lewisville breathalyzer and blood test defense lawyer may be able to help you. With an established focus on DWI cases, an attorney will understand the nuances of defense needed, with knowledge on how to detect potential flaws, negligence on the part of the officer, or other errors that may have occurred when the tests were administered. Additionally, an attorney will understand how to collect necessary evidence on your behalf to dispute the charges.
Ways a Lawyer May Be Able To Defend You in Your DWI Case
A lawyer may be able to help you with your DWI case in a variety of ways. Among the most important is the possibility of being able to prove there was an error in your breathalyzer or blood test. Here are some of the points of interest your lawyer may be able to argue on your behalf:
- There is a large margin of error for an accurate breathalyzer test
- Even a minor error, mechanical issue, or processing mistake may prove your innocence
- A defective breathalyzer device, whether outdated or improperly maintained, can result in false readings
- A breathalyzer device may have been inaccurately used by the officer, resulting in an incorrect reading
- There was a lack of a probable cause to require the use of a breathalyzer test
- Proper protocol was not followed in administering the test by the officer
