A breath test measures the amount of alcohol in exhaled air. A blood test analyzes alcohol concentration in a blood sample. In Illinois, the results can influence penalties and enforcement actions.

Understanding these elements helps you determine whether a challenge to the result may be appropriate in your case.
Key elements include sample collection, device calibration, measurement, documentation, and the chain of custody.

Key terms commonly appear in breath and blood testing cases. Understanding terms like breath sample, BAC, calibration, chain of custody, and lab report helps you engage in informed discussions about your case. This glossary provides brief definitions and explains how each term relates to the testing process and to the potential defenses available in a Manteno DUI matter.
Breathalyzer is a device used to estimate alcohol in breath and infer blood alcohol content. It relies on a sensor or chemical reaction and must be maintained correctly. Factors such as temperature, humidity, and operator procedure can affect results. Challenges may focus on calibration and adherence to testing protocols.
Blood Alcohol Concentration or BAC indicates the level of alcohol in the bloodstream at the time of testing. It is used to assess impairment under state law. Results depend on proper sample handling, timely testing, and accurate measurement. Questions about timing, storage, and lab procedures may form part of a defense strategy.
Calibration and maintenance describe how devices are set to measure alcohol levels and kept in good working order. Regular calibration against known standards, date stamps, and service logs support reliable readings. When records are missing or procedures were not followed, a defense may be built around potential measurement issues.
Legal standards define how tests are administered and interpreted under Illinois law. Chain of custody refers to the documented sequence of who handled the sample and when. Any breaks in custody, improper storage, or protocol deviations can impact test credibility and admissibility.
