What does the instrument detect and measure?

• A. Detect blood glucose
• B. Measure CO2 in breath
• C. Detect drug metabolites in urine
• D. Detect and measure alcohol in breath

Answer: (D)

The instrument’s purpose is to detect and measure ethanol in the breath to estimate the wearer’s blood alcohol concentration. When you blow into it, the device analyzes the alveolar air for alcohol molecules and produces a signal proportional to the ethanol concentration. That signal is then translated into a BAC value using a standard breath-to-BAC relationship (the blood-to-breath partition ratio). It’s designed specifically to quantify alcohol, not to detect glucose, CO2, or drug metabolites in urine.
