Phoenix DUI Charges: Blood Tests

Typically considered more accurate than a breath test, a blood test may be administered after a Phoenix driver is arrested for suspected DUI (driving under the influence) in order to determine his or her blood alcohol concentration or whether a controlled substance is present in his or her system. Depending on the results of this test, a driver may face criminal charges for driving under the influence of alcohol or drugs.

Common Problems with Blood Tests

Although it is true that a blood test may be more accurate than a breath test, as it measures the level of alcohol in the subject's blood as opposed to their breath, theses tests may have inherent faults and may be subject to mistakes made by the individual administering or handling the test. A DUI lawyer with the knowledge and resources to properly investigate the outcome of a blood test can have an independent analysis of the blood sample conducted and can bring to light such issues as:

• The person who administered the test was not properly trained or qualified to do so.
• The test was administered improperly or in violation of state procedure.
• The blood sample was tested improperly, meaning the result was incorrect.
• The blood sample was not properly mixed with anticoagulants and preservatives.
• The blood sample was mishandled, such as due to a break in the chain of custody.

Immediately involving an attorney is one of the most important steps you can take if you were arrested for drunk driving and were told that you failed a blood test. In addition to protecting your legal rights in criminal court proceedings, a skilled lawyer can help you at your MVD hearing, which will be held regarding the administrative suspension of your driver's license. The outcome of your blood test may play a crucial role in both criminal and MVD proceedings.
