FAQ

How is BAC measured? The different bodily samples that can tell a person’s BAC include urine, saliva, hair follicles, blood, and breath. Only breath analysis and blood screening are most commonly used by law enforcement when it comes to a DUI case. However, breath is the chosen method most of the time because blood tests are still seen as invasive.

How does a Breathalyzer test actually work? This is a machine that analyzes a suspect’s blood alcohol concentration, like many others on the market. They do this by measuring alcohol content of exhaled vapor through infrared spectroscopic analysis.

Are Breathalyzer tests accurate? They are not as accurate as blood tests; however, they are seen as acceptable to gather evidence. The only issue is that studies have found that the breath readings on a Breathalyzer can vary by 15% from actual BAC levels. This has posed the question: Are they as reliable as people say? Flaws usually stem from design problems, variance in the temperature of the machine, body temperatures of the test subjects, and hematocrit in the blood.

If you’re intoxicated, is there any way to beat a Breathalyzer test? People sometimes try breath mints, mouthwash, onions, and pennies. However, this is not the case, and it will not happen. 

Can you challenge Breathalyzer results in court – and win? Yes. These machines must be tested constantly to make sure they are calibrated correctly. If the evidence is not valid, you have a case, so this is important to find out.
