Blood & Breath Tests

Blood and breath tests are a normal part of all DUI cases, as they are ways of determining whether or not a driver was under the influence of alcohol while they were operating a motor vehicle. Both blood and breath tests are used to determine a person’s blood alcohol concentration (BAC) and the results of these tests can be used as evidence to prove guilt in DUI cases.  If you have taken a blood or breath test that revealed your BAC to be .08 percent of higher, you should speak with Jefferson County DUI lawyer Chris Cessna.  As an experienced DUI defense attorney, Mr. Cessna knows how to challenge the results of your blood or breath test in order to have your charges reduced or dismissed.

Blood Tests

When a blood test is conducted, a sample of the suspect’s blood will be drawn and will then be analyzed to determine the amount of alcohol present in the blood.  If the person’s blood is found to contain .08 percent or more of alcohol, they can be charged with DUI.  It is important to note that blood test results are not always 100% accurate, and different factors may lead to a false result.  Certain health conditions of the test subject may cause an inaccurate BAC, and if the sample is improperly drawn or stored it can also lead to a result that is inaccurate.  Jefferson County DUI attorney Chris Cessna will thoroughly examine the results of your blood tests to determine whether or not your BAC was inaccurate.

Breath Tests

Breath tests are performed through the use of an instrument called a breathalyzer, which measures the amount of alcohol present in the blood by testing the air in the lungs.  These machines have been known to produce inflated BAC results when certain environmental conditions or health conditions are present.  The machines themselves have also been known to malfunction or be improperly calibrated or maintained, and in certain cases this may lead to an inaccurate reading.  As a certified and trained operator of the Intoxilyzer 5000 (a breath testing machine) DUI lawyer Chris Cessna is highly qualified to challenge the results of this test and will take the necessary measures to have your breath test results deemed as inadmissible evidence in your DUI case.
