An Overview of Breath and Blood Tests

Chicago DUI Attorney

If you or a family member has been accused of driving under the influence of alcohol or drugs, you could be facing very serious penalties. During this confusing and often frightening time, you need a Chicago criminal lawyer that you can trust to be on your side. If you were pulled over by a law enforcement officer because of suspected drunk driving, you will be asked to consent to either a chemical or field sobriety test to determine your level of intoxication.

Breath Tests

One of the primary tests used to determine a driver's blood alcohol content (BAC) is the breath test, also called a Breathalyzer test. This test is administered at the scene by law enforcement and is supposed to measure the amount of alcohol in the deep lung region. While the results of these tests are often used by prosecution, this method of measuring a driver's BAC is often very flawed. In many cases, the arresting officer improperly administers the test, and the machines are known to malfunction if they do not receive routine maintenance.

Blood Tests

The other test commonly used to determine BAC is a blood test. The driver's blood is drawn at the police station or an approved laboratory. The sample is then analyzed by a trained technician to determine the driver's BAC. This evidence is not foolproof, as laboratory staff can contaminate the sample by a failure to follow standard procedures, mislabeling the samples, or making other mistakes.
