Blood Alcohol Testing

Blood alcohol concentration (BAC) is the total amount of alcohol in an individual’s body, measured by the weight of the alcohol in a volume of blood. Generally, there is wide variation in alcohol tolerance among individuals and therefore the predominant effects may vary. The effects of alcohol vary from person to person; some users may become intoxicated at a much lower blood alcohol concentration.

An individual’s BAC depends upon many factors including, gender, weight, metabolism, time period over which the alcohol was consumed and the amount of food in the stomach prior to drinking. Although a person’s BAC can be estimated, the level cannot be determined solely by the number of drinks consumed, and cannot be precisely calculated by a person’s height and weight.

The following Blood Alcohol Concentration Charts will show you the difference of BAC level from one to nine drinks for anyone from 100 to 240 pounds. One drink is equal to one 12oz. light beer with an alcohol concentration of .042%, 3-5 oz. glass of wine, 1 ¼ oz. of 80 proof liquor, or 1oz. of 100 proof liquor.
