What is the term used to describe the amount of alcohol in the bloodstream?

• A. Breath Alcohol Content
• B. Alcohol Concentration in Blood
• C. Blood Alcohol Level
• D. Blood Alcohol Concentration

Answer: (D)

The concept tested is the standard term for how much alcohol is in the bloodstream, described as a concentration. This describes how much alcohol is present per unit of blood, typically measured in grams per deciliter (g/dL). It’s the term used across medical, scientific, and legal contexts to indicate intoxication levels and to set legal limits.

Blood Alcohol Concentration is the precise, widely accepted phrase for this measure. It captures the idea of a quantity described as a concentration, not just a total amount or a qualitative label.

Breath Alcohol Content refers to the amount detected in the breath, which breath tests estimate to infer BAC but is not the direct blood measurement. Alcohol Concentration in Blood is understandable but is not the standard, established term. Blood Alcohol Level is commonly understood but not the formal, preferred terminology.
