Facing a driving under the influence (DUI) charge in Georgia can feel like you have limited options, especially when blood test results are involved. You may assume the numbers alone decide your fate, but the testing process involves multiple steps that can affect accuracy. Paying attention to these details can reveal weaknesses in the evidence and create opportunities to strengthen your case.
Where the numbers come from
Blood tests in DUI cases must follow strict procedures. Even minor errors can carry significant consequences. If an arresting officer does not follow the steps outlined in O.C.G.A. § 40-6-392, the resulting blood test may be challenged or even deemed inadmissible.
Using the wrong type of vial, delaying testing or relying on poorly calibrated machines can all compromise the reported blood alcohol content (BAC). Understanding how the process works may set the stage for reviewing possible errors.
Common mistakes that shake results
Once you know how the testing process works, it becomes easier to see where problems might arise. Several factors can make blood test results less reliable:
- Using improperly trained staff to draw the blood sample
- Contaminating or mishandling blood during storage or transport
- Using faulty or uncalibrated testing equipment
- Experiencing medical conditions that naturally raise BAC levels
- Testing at different times after driving
Looking at these potential errors often requires a careful review of lab reports and medical records. Examining the evidence alongside an experienced attorney can reveal small but important details that might change how your case unfolds.
Turning weaknesses into leverage
After identifying possible weaknesses, challenging the blood test evidence can shift how your case is viewed in court. Highlighting errors in collection, storage or analysis may lead to reduced penalties or open the door to alternative resolutions.
Focusing on these details shows that BAC results are not always absolute and that careful examination can create meaningful opportunities for your defense.
Protecting your future one step at a time
Challenging blood test evidence starts with paying attention to each step of the testing process. Even small mistakes can change how a judge or jury interprets the results. By carefully reviewing these details, you can see the bigger picture of your case and weigh your options for moving forward with confidence.
