Blood tests analyze the chemical composition of the sample taken from the suspect to determine whether the blood alcohol concentration is above the legal limit. A BAC over .08% can lead to a per se conviction for DUI even when there is no other evidence of intoxication. These tests are in many ways superior to field sobriety tests and breath tests, but are still subject to error. You are innocent until proven guilty, and an attorney from the firm may be able to exploit weaknesses in the test results to help you avoid the significant DUI penalties you could receive if convicted.

Blood Testing in Phoenix DUI

Tracking the handling of the sample is among the most important aspects of challenging blood test results in a DUI case. Any error or gap in the records makes it possible to cast doubt on the reliability of the evidence, which could lead to a dismissal of the charges. Another proven strategy involves demonstrating that the test sample could have been contaminated, as this can lead to fermentation resulting in a false positive. Other factors, including improper calibration of the testing equipment and operator inexperience, can also be used to invalidate the test results. Let an attorney from the firm review the circumstances of your case to find the most effective strategy for defending your rights.
