These devices offer a rapid method for estimating blood alcohol content (BAC) through the analysis of oral fluid. A small sample of saliva is applied to the strip, which contains chemically reactive pads that change color in relation to the alcohol concentration present. For instance, a color shift indicating a higher alcohol level suggests greater impairment.
The significance of these screening tools lies in their ease of use, portability, and speed, allowing for immediate assessment in various situations. Historically, more invasive procedures, such as blood draws, were required for alcohol level determination. These strips provide a non-invasive alternative, facilitating timely interventions and promoting safer environments in settings ranging from law enforcement to healthcare and workplace safety programs.
