What principle does a blood glucose monitor operate on?

• A. It uses light reflection to determine glucose levels
• B. It measures glucose levels through a chemical reaction
• C. It utilizes electrical conductivity to assess sugar content
• D. It collects data via temperature fluctuations in blood

Answer: (B)

A blood glucose monitor operates on the principle of measuring glucose levels through a chemical reaction. Most modern blood glucose monitors use an enzymatic method involving glucose oxidase or similar enzymes. When a blood sample is applied to a test strip containing these enzymes, a chemical reaction occurs that produces an electrical signal proportional to the amount of glucose in the sample. This electrical signal is then processed by the monitor to provide a glucose level reading. This method is preferred for its accuracy and reliability, which are critical for managing diabetes effectively. The enzymatic reaction not only allows for precise measurements but also ensures that the monitor can provide rapid results, which is essential for users who need to monitor their blood glucose levels frequently throughout the day.
