Alcohol testing refers to the process of measuring the amount of alcohol present in a person's system. This is commonly done using breath, blood, or urine tests. The results help determine if an individual is under the influence of alcohol, which is important for law enforcement, workplace safety, and medical assessments. Breathalyzers are a popular tool for alcohol testing, providing quick results by analyzing a person's breath. Blood tests are more accurate and can detect alcohol levels over a longer period. These tests are essential for ensuring public safety and compliance with laws regarding alcohol consumption, especially for drivers and employees in safety-sensitive positions.
