Fighting blood test results in a Florida DUI case involves questioning the accuracy, legality, and handling of the blood sample. Here’s a summary of how we challenge blood test results:

​

1. Examine the Collection and Handling Procedures

​

Proper Collection Protocol:

Certified Personnel: Ensure that the blood sample was collected by a qualified medical professional, such as a nurse or phlebotomist, who is trained to perform the procedure correctly.

Correct Procedure: Verify that the blood was drawn according to proper medical and legal procedures. Improper collection techniques, such as not using the correct antiseptic or using unsterilized equipment, can lead to contamination and affect the test results.

​

Chain of Custody:

Documentation: Review the chain of custody records to ensure that the blood sample was handled and stored properly from the time it was collected until it was tested. Any break in the chain of custody can lead to contamination or tampering concerns.

Storage Conditions: Check if the blood sample was stored under the correct conditions. Improper storage (e.g., incorrect temperature) can affect the integrity of the sample.

 

2. Challenge the Accuracy of the Blood Test

​

Testing Procedures:

Lab Accreditation: Confirm that the laboratory conducting the test is properly accredited and follows standardized procedures for testing. An unaccredited or improperly equipped lab may produce unreliable results.

Quality Control: Check if the lab has proper quality control measures in place. This includes regular calibration of equipment and adherence to protocols.

​

Testing Methodology:

Accuracy of Tests: Review the specific testing methodology used (e.g., gas chromatography). Each method has its own accuracy levels and potential for error.

Test Results: Obtain and review the lab’s test results and any relevant documentation. Look for any inconsistencies or errors in the test report.

​

3. Examine Potential Sources of Error

​

Sample Contamination:

Contamination Risks: Investigate whether there was any potential for contamination of the blood sample during collection, handling, or storage. Contamination can affect the accuracy of the test results.

​

Medical Conditions:

Health Issues: Certain medical conditions, such as diabetes or gastrointestinal disorders, can affect blood alcohol levels and potentially lead to inaccurate results. Provide evidence of any relevant medical conditions.

​

Interfering Substances:

Substance Interference: Check if there were any substances (medications, mouthwash, etc.) that could have interfered with the test results. Some substances can affect the accuracy of blood alcohol readings.

​

4. Consult with Experts

​

Forensic Toxicologists:

Expert Review: Hire a forensic toxicologist or a DUI expert to review the blood test procedures, results, and any potential issues. An expert can provide a detailed analysis and testimony regarding the reliability of the test results.

​

Lab Practices:

Expert Testimony: An expert can testify about standard practices and potential deviations that may have occurred, which can help challenge the validity of the test results.

 

5. Legal and Procedural Challenges

​

Legal Protocols:

Adherence to Legal Procedures: Ensure that all legal procedures related to blood testing were followed, including obtaining necessary warrants and consent (if applicable). Any violations of legal protocols can be used to challenge the results.

​

Rights Violations:

Constitutional Rights: Evaluate if your constitutional rights were violated during the arrest or testing process. Violations of rights can impact the admissibility of evidence in court.

 

6. Challenge the Prosecutor’s Evidence

​

Cross-Examination:

Witness Testimony: Cross-examine the prosecution’s witnesses, including the arresting officers and lab technicians, to uncover any inconsistencies or errors in their testimony and handling of the case.

​

Alternative Explanations:

Alternative Factors: Present alternative explanations for the blood alcohol levels, such as medical conditions or potential errors in the testing process.

​

Conclusion

​

To effectively challenge blood test results in a Florida DUI case, we must investigate every aspect of the collection, handling, and testing process. We scrutinize the procedures, examine potential sources of error, consult with experts, and address any legal or procedural issues. We will build a strong defense to effectively challenge the blood test results.
