What determines blood alcohol concentration?
Blood alcohol concentration, or BAC, is the metric used to measure the amount of alcohol in a person’s bloodstream at a given time. This alcohol content can be determined by testing the person’s breath, blood, urine, or saliva, with breath testing being the most common method of testing as practiced by law enforcement.

How much is 0.5 alcohol in the blood?
Physiological effects of various blood alcohol levels
| Blood alcohol level | Physiological effect |
|---|---|
| 0.4–0.5% (400–500 mg/dL) | Potentially fatal and a person may be comatose. |
| Above 0.5% (500 mg/dL) | Highly dangerous/fatal blood alcohol level. |
How do you read alcohol percentage?
