A blood alcohol tester, commonly described as a breathalyzer, determines the concentration of alcohol or ethanol in a body. Police often use breathalyzer tests at random obstructions or for medical functions to check that people are driving safely; or to carry out medical analysis. A breathalyzer test typically involves blowing into a device; it can also include analysing saliva samples or urine samples collected throughout hospital or physician workplace visits for analysis purposes.
Alcohol has numerous harmful results on the body, from reducing coordination and hindering judgment, to intoxication with high Blood Alcohol Concentrations (BAC), making them incapable of driving safely or controlling their behavior.

An innovative kind of breathalyzer, the infrared spectrometer utilizes infrared light to discover alcohol in breath and blood samples with more precision than traditional breathalyzers.
Numerous people try to deceive a breathalyzer utilizing special substances and techniques; nevertheless, these strategies do not always work and may result in incorrect favorable results. One efficient technique to avoid incorrect positive outcomes is by avoiding alcohol for a minimum of 24 hours prior to taking a test.
