Breath and Blood Tests

Chicago DUI Attorneys

Breath, blood and urine tests are used to determine a driver’s blood alcohol concentration (BAC) or the presence of narcotics or other controlled substances following a DUI arrest. A driver may face Statutory Summary Suspension for failing a breath test, blood test or urine test, or for refusing chemical testing altogether. This is an automatic license suspension which will take place on the 46th day after you receive the notice. However, you have the right to challenge your driver’s license suspension, and a Chicago DUI attorney at Fagan, Fagan & Davis can help.

The attorneys at our firm are experienced in challenging breath and blood test results in criminal proceedings, and with representing clients in Summary Suspension matters in order to protect not only their rights and freedom but their driving privileges as well.

Challenging Illinois Breath and Blood Tests

There is no way that a single breath test can be 100% accurate in determining a driver’s blood alcohol concentration. If this is off even by a fraction of a percent, this can mean the difference between a legal alcohol level and one that will result in criminal charges. Additionally, blood tests are subject to any of a number of faults, including in how the sample is handled, mixed and analyzed, as well as who takes the blood sample.

Consult a Chicago DUI Lawyer

A Chicago DUI lawyer can review all aspects of your breath test or blood test, the qualifications of the person who administered the test and the methodology used in analyzing the sample in order to determine exactly how to build a strong defense on your behalf to contest these results. It may be that the breath test machine was improperly calibrated, that the person who administered the test was not licensed to do so, that the person who administered the test had an expired license to administer the test, or that the blood sample was mishandled in some manner or analyzed in an unreliable manner. There are numerous ways chemical testing can go wrong.  It is up to your attorney to discover the facts and then apply their knowledge to your particular case.
