Breath Alcohol Tests
Breath alcohol tests, commonly called "breathalyzers" or "BATs", are instant screenings that determine current intoxication levels. A BAT measures the presence of alcohol in a person's breath. Using "Henry's Law", scientists agree that the percentage of alcohol in the vapor of a person's breath correlates to the percentage of alcohol in that person's bloodstream. As compared with blood tests , breath testing for alcohol is far more convenient, less invasive, much faster, and equally accurate. Thus, breath alcohol tests have become the ubiquitous methodology for employers, the US Department of Transportation, and law enforcement.
