What is an initial screening test for alcohol testing called?

An initial screening test for alcohol testing is commonly referred to as a breathalyzer test. This type of test is designed to measure the concentration of alcohol in an individual's breath, which is then used to estimate the blood alcohol content (BAC). The breathalyzer is widely used because it provides immediate results, is non-invasive, and is portable, making it convenient for use in various settings, such as roadside checks or workplace testing.

In the context of alcohol testing, this initial screening is crucial as it helps determine whether further, more detailed testing, such as blood or urine tests, is necessary. Other methods, such as field sobriety tests, assess an individual’s physical and cognitive abilities but do not directly measure alcohol levels. Similarly, blood tests are typically used for confirmatory purposes after an initial test has indicated possible alcohol consumption, and urine tests can detect alcohol but are less common for immediate screening.
