Challenging Blood Test Results in Tennessee DUI Cases: Legal Strategies

At Huffman Mason, PLLC, we understand that facing DUI charges can be a daunting experience. Blood test results often play a crucial role in these cases but are not infallible. With the right legal strategies, it's possible to challenge blood test results and build a strong defense. In this article, we'll delve into some effective approaches we employ to challenge blood test results in Tennessee DUI cases.

Scrutinizing the Testing Process

One of the initial steps in challenging blood test results is closely examining the testing process. Our experienced legal team meticulously reviews the procedures law enforcement and medical professionals followed during the blood collection, transportation, and testing phases. Any deviation from established protocols could potentially compromise the accuracy of the results.

Chain of Custody Examination

Maintaining the chain of custody is critical in preserving the integrity of blood samples. We scrutinize every step of the chain of custody to identify any mishandling or inconsistencies that could raise doubts about the reliability of the results. Even the slightest deviation can be used as a compelling argument in court.

Analyzing Laboratory Protocols

Our dedicated legal experts delve into the specific protocols followed by the laboratory that conducted the blood test. Any procedural errors, equipment malfunctions, or inadequate calibration can be brought to light to challenge the accuracy of the results. By questioning the reliability of the laboratory's procedures, we aim to create reasonable doubt in the minds of the judge and jury.

Medical Records Examination

Certain medical conditions or medications can significantly affect blood test results, leading to falsely elevated blood alcohol concentration readings. We carefully review the defendant's medical history and current prescriptions to identify potential factors that might have influenced the test results. Presenting such information to the court can remove doubt about the blood test's accuracy.

Rising Blood Alcohol Defenses

In some cases, individuals may have been pulled over and arrested while their blood alcohol concentration was still rising due to recent alcohol consumption. Our legal team works to establish a timeline that demonstrates the possibility of the defendant's blood alcohol level being lower at the time of driving and higher at the time of testing. This can be a strong defense strategy to challenge the prosecution's narrative.

Inaccurate Equipment Calibration

Blood alcohol testing equipment requires regular calibration to ensure accurate readings. If there is evidence that the equipment used in the blood test was not properly calibrated, it can be argued that the results may not be reliable. We meticulously investigate whether the testing equipment used in the case was appropriately maintained and calibrated.

In Tennessee DUI cases, blood test results are often presented as concrete evidence of guilt. However, challenging these results requires a comprehensive understanding of the legal and technical aspects. At Huffman Mason, PLLC, we are committed to providing rigorous defense strategies tailored to each client's unique situation.
