Fighting WI DUI Blood Test Results

In Wisconsin, police officers are allowed to take a blood sample to determine if you were driving drunk. You give up this right when you obtain an driver’s license under the Implied Consent Law.  After your blood is drawn, it is sent to the Wisconsin State Laboratory of Hygiene and tested to determine your blood alcohol concentration. If the police officers requested a test for alcohol only you should expect to receive your test results back in 2-3 weeks. If a request was made for a drug panel to be performed, you should expect to wait anywhere from 9 months to a year for a result.

Blood results are widely considered to be the most accurate test for determining alcohol and drug levels. An experienced Wisconsin DUI Lawyer will know how to level the playing field by analyzing your results and the procedures used to determine if any defenses exist to attack the blood result.
