Is using an AlcoTester an accurate way to measure blood alcohol concentration (BAC)?

Using an AlcoTester can provide a relatively accurate measure of blood alcohol concentration (BAC). These devices utilize breathalyzer technology, which estimates BAC levels by analyzing exhaled breath for alcohol content. While AlcoTester results can give a good indication, it is important to note that they are not as precise as a blood test performed in a professional lab environment. Factors such as user error, device calibration, and the consumption of substances other than alcohol can affect accuracy. Despite these limitations, AlcoTester devices are widely used by individuals and law enforcement agencies for preliminary BAC screening. It's worth noting that relying solely on an AlcoTester reading may not be admissible as evidence in a court of law, so professional testing is necessary for legal purposes.
