DUI blood tests in Arizona are sometimes performed in order to determine the blood alcohol level of a person suspected of driving under the influence. While blood tests are generally more accurate than breath tests, certain factors can affect their results as well. The state of Arizona uses special kits that involve a vacuum tube coated with chemicals in order to preserve the sample and prevent coagulation.
These kits require the person drawing the blood and the officer present to mix the blood in a tube according to a set protocol. If the blood is drawn incorrectly, if the chemicals are not present in the proper amount, or if the proper protocol is not followed, results will be inaccurate.

What is Involved in a DUI Blood Test?If you agree to a blood test in relation to suspicion for DUI, only a person trained in blood withdrawal can take a blood sample. The person responsible should be careful not to allow alcohol from a swab to contaminate the blood drawn. If a NIK kit is used, the person taking the sample is supposed to mix the blood by rotating the tube end to end 5 times. Afterwards, the officer present is instructed to take the tube and rotate it an additional 20 times. In both cases, the sample should not be shaken but gently rotated back and forth to allow for a proper mixing of the blood.
What Could Compromise the Accuracy of the Results?Any number of things can go wrong in a blood test:
Every Arizona DUI arrest and every police officer is different. Our DUI defense carefully reviews the specifics of your Arizona DUI arrest, how blood was drawn, the chain of evidence, and whether the lab has undertaken quality control measures to ensure the accuracy of its tests. When necessary, we consult with lab technicians, chemical analysts, and forensic specialists in defending our client’s innocence.
