What does blood alcohol testing measure?

Blood alcohol testing specifically measures the amount of alcohol present in the bloodstream at a given time. This measurement is quantified in terms of Blood Alcohol Concentration (BAC), which indicates the percentage of alcohol in a person's blood. Understanding this concentration is crucial for various applications, such as legal, medical, and health reasons, as it directly reflects the level of impairment and potential effects on the body.

While the effect of alcohol on driving ability, the time taken to detoxify alcohol, and the presence of alcohol in breath are relevant topics, they are not the primary focus of blood alcohol testing. This test is solely concerned with quantifying the amount of alcohol in the blood to assess an individual's level of intoxication at the time of testing.
