Breath & Blood Tests

Breath and blood tests are performed to determine the presence of alcohol or controlled substances in a person’s system.  If a motorist's blood alcohol concentration is discovered to be .08 percent or higher, they are considered to be over the legal limit and can be charged with DUI.  If a blood test or urine test shows the presence of illegal narcotics or other controlled substances, the driver may also face DUI charges. Breath and blood tests are considered to be relatively accurate ways of determining a person’s BAC, especially when combined and compared with field sobriety tests.  The attorneys at our firm understand that although blood and breath testing is a more accurate way of finding out what an individual’s BAC is, it is not always 100% accurate.

Many people in DuPage County express feeling hopeless after taking a blood or breath test that revealed their BAC to be above the legal limit.  Our lawyers always urge these people not to give up hope because there are ways of contesting the results of a blood or breath test.  Even under the best circumstances, blood and breath testing machines are subject to error and it is important that you have a DuPage County DUI defense attorney who is capable of challenging this mode of testing. 

Breath Testing

Breath testing machines are subject to human error, technical malfunctions, and maintenance problems, all of which can lead to an inflated and inaccurate blood alcohol content evaluation.  Your DUI defense lawyer will examine the testing equipment used during your breath test and will also take into consideration how the equipment was used and any other pertinent conditions that may affect the test results.

Blood Testing

Discrepancies occur all the time with blood testing and sometimes the blood sample can be drawn incorrectly, or improperly handled or stored.  Other times the defendant can have existing medical conditions which may inflate the blood alcohol content in the sample.  In any case, your attorney will take the proper measures necessary to find any problems in the blood test you were given.
