Have you ever wondered how they work? A breathalyzer test essentially detects the presence of alcohol in your breath. However, there are other things beside your favorite cocktail that contain alcohol and any number of them could potentially lead to a false positive result.
DUIs are treated seriously throughout the country, given that drinking and driving is a major leading cause of fatal car accidents. Law enforcement officers often pull over drivers who swerve, drive erratically, or show other telling signs of intoxication they are trained to look out for. If you are pulled over for a suspected DUI, you will be asked to submit to a breathalyzer test. While many of us accept that these tests are generally infallible, the truth is that they are far from perfect and false readings are not as uncommon as you might think.
Other culprits beside breath fresheners can cause a breathalyzer to provide a false positive result. Police officers are not perfect and, while calibrating the breathalyzer, he or she might set it incorrectly. Unfortunately, these mistakes cost others and a simple error in calibration can lead to multiple arrests based on inaccurate information. A breathalyzer test is a machine and, like all machines, it needs to be regularly maintained to ensure the information it is providing is as precise as possible. Without proper calibration or upkeep, officers will undoubtedly make arrests that cannot be supported in court, creating serious hardships for innocent citizens.
Breathalyzer tests measure a driver’s breath alcohol content, or BrAC. The BrAC numbers are then converted into BAC numbers. When people consume alcohol, the alcohol travels through the esophagus, into the stomach and to the small intestine. There, the alcohol diffuses into the bloodstream.
Police officers also use breathalyzers more often because they produce breath test results very quickly. A BAC reading can happen in a matter of seconds. Blood tests require lab work. This can delay the blood test results for multiple hours. In the meantime, police have to hold the suspect in custody.
There, the alcohol diffuses into the bloodstream. In the bloodstream, the alcohol circulates throughout the body. This takes it through the lungs. There, some of the alcohol in the blood diffuses into the lungs. Once in the lungs, it is released whenever the person exhales.
Law enforcement officers are more likely to use a blood test if the incident involved a car accident and the drunk driving suspect is hurt and in the hospital, already. In these cases, medical professionals are often already administering a blood draw. Police then request that it be tested for its blood alcohol level.
Breath tests only indirectly measure someone’s BAC . Blood tests are also less susceptible to environmental factors that can skew the results. Unlike breath tests, blood tests take a sample of a DUI suspect’s blood and measure the amount of alcohol in the sample.
Breath tests can produce false positives if there is latent alcohol in the suspect’s mouth. This can happen if the driver: recently used mouthwash or a breath freshener, has not eaten in a while, burps soon before the breath test is administered, bringing extra alcohol up from the stomach into the mouth,
