Tampa Blood Test Challenge Lawyer
If your DUI arrest in Tampa involved a blood test, the outcome of your case may hinge on that single vial. But blood test results are not always reliable. Florida law places strict requirements on how law enforcement officers collect, transport, and test your blood sample. One mistake can mean the difference between a DUI conviction and a case dismissed.

How Blood Tests Work in Hillsborough County DUI Investigations
In DUI cases across Hillsborough County, a blood draw may be used when a breath test is unavailable or when serious bodily injury is involved. Some people are unconscious after a crash. Others are taken to the hospital instead of central booking. In these moments, law enforcement may request a blood test under Florida’s implied consent laws.
Blood tests are considered highly accurate—but only when done correctly. The sample must be drawn by a qualified professional, stored properly, and tested using approved chemical tests. If any step is skipped, the test results can be challenged in court.
Real Issues That Affect Blood Test Reliability
We’ve seen DUI cases where blood test results were delayed for weeks. In some, the chain of custody broke down, with unclear records showing who handled the blood sample. In others, the sample was stored at the wrong temperature or tested outside the standard operating procedures required by Florida statute.
Medical conditions and prescription drugs can also affect blood alcohol concentration. If your blood sample included contamination or if your DUI investigation skipped required steps, those test results may not hold up.
How a DUI Lawyer Challenges Blood Test Evidence
A Tampa DUI lawyer who understands DUI blood tests knows what to look for. Was the draw authorized under Florida law? Was the arrest lawful? Did the arresting officer follow protocol? Each detail matters.
Your attorney can request documentation on the testing procedures, chain of custody, and the qualifications of the person who drew the blood. If there are errors, they can raise legal arguments that create reasonable doubt or block the prosecution’s evidence from being used at trial.
A Skilled Defense Strategy Can Change the Outcome
Blood test evidence may seem final, but it is not. With an experienced attorney, you can challenge how the evidence was obtained and whether it meets the legal standard for your DUI case. Many Florida DUI cases involving blood tests fall apart when exposed to real scrutiny.
An effective defense strategy is not about technicalities—it is about protecting your rights and ensuring fair treatment under the law. If your blood draw was flawed, your entire case could be open to dismissal.

Frequently Asked Questions About DUI Blood Tests in Tampa
Can I refuse a blood test during a DUI investigation?
Refusing a blood test may lead to license suspension under Florida’s implied consent laws. However, if the request was not legal, your attorney may be able to fight the suspension and the evidence.
What can make a blood test inaccurate?
Improper storage, broken chain of custody, unqualified personnel, and outside interference can all affect test results. Even medical conditions or prescription medications may play a role.
Can a lawyer get my blood test thrown out?
Yes, if your DUI defense attorney can show that the blood sample was mishandled or collected in violation of Florida law. The court may suppress the results.
Are blood tests more accurate than breath tests?
In theory, yes. But blood tests also come with more strict guidelines. When those are violated, the results become unreliable.
How can I know if there was a mistake in my blood test?
Your lawyer can request all documents related to your blood sample, including who drew it, how it was stored, and how it was tested. This is key to building a strong defense.
