Blood vs. Breath vs. Urine Testing in Hillsborough County DUI Cases

Breath Testing (Most Common)

Breath testing is the most common type of chemical testing used when someone is arrested for a Hillsborough County DUI. Officers will typically request a breath sample through an Intoxilyzer 8000, a device approved for evidentiary breath testing in the state of Florida.

While breath testing allows for quick results, it is not always perfect and can be affected by factors such as calibration issues, improper maintenance, or operator error. A DUI lawyer in Tampa at The Law Office of Timothy Sullivan can review the facts of your case and determine whether the results can be challenged.

Blood Testing (Less Common, More Invasive)

Blood testing is less common compared to breath testing and is typically used for more serious DUI investigations. For instance, law enforcement might request a blood test if the crash caused a serious injury or death, or if required by law. 

The blood draw usually occurs at a hospital or medical facility and could require a warrant if consent is not already provided. While blood tests are generally considered more accurate than breath tests, questions can still arise regarding how the sample was collected, stored, transported, and tested. 

An experienced DUI lawyer in Tampa can review the blood test and identify any factors that may affect the reliability of the results.

Urine Testing (Drug-Related DUIs)

Urine testing is most often used when officers suspect that a driver is impaired by drugs rather than alcohol. Although these tests detect the presence of certain substances in the body, they do not necessarily prove that a driver was impaired at the time of driving.

A person can test positive for a substance long after the effects of the drug have worn off. For this reason, urine testing has several limitations and can sometimes raise reliability concerns in court. A DUI lawyer in Tampa can challenge urine test results by examining testing timelines, possible false positives, prescription medications, or other medical explanations.

Refusal Consequences in Florida

When someone has been arrested for a DUI, refusing to participate in a chemical test can come with serious consequences under Florida law. For a first refusal, an administrative driver’s license suspension is possible even if a DUI conviction does not occur. Additionally, prosecutors might use evidence of the refusal in court to argue that testing was denied because the person believed the results would have been unfavorable. Additionally, a first refusal is now a Second Degree Misdemeanor in the State of Florida.

While the consequences are not to be taken lightly, they can differ depending on whether the test involved breath, blood, or urine testing, especially when warrants or special circumstances are present in the case. Because of these variations, as well as the legal complexities involved, it is crucial when facing a DUI case to speak with an experienced DUI attorney as soon as possible.
