What specific feature allows the blood glucose meter to display glucose concentration?

• A. Measurement of volume used
• B. Measurement of reaction completion time
• C. Measurement of the current produced during oxidation
• D. Measurement of pressure changes in the sample

Answer: (C)

The blood glucose meter displays glucose concentration by measuring the electrical current produced during the oxidation of glucose. In this process, glucose in the blood sample is oxidized by a specific enzyme, typically glucose oxidase. This reaction generates electrons that flow through an electrode, creating a measurable electrical current. The magnitude of the current is directly proportional to the concentration of glucose in the sample. This method allows for a quick and accurate assessment of blood glucose levels, which is critical for managing conditions such as diabetes. The current generated corresponds to glucose concentration, which the meter translates into a glucose reading that the user can easily interpret. This electrochemical detection is a key feature of modern glucose meters, making them user-friendly and efficient for home monitoring.
