  • Since they store your previous readings in their memory, a blood glucose meter serves as a record of your results, allowing you to develop a pattern.
  • You will know how your body is responding to certain medicines, exercise and food items
  • The pattern of your readings will help your doctor determine a picture of how your treatment is working out

How does a glucometer work?

The test strips that come with the device are made up of an enzyme called glucose oxidase. This enzyme oxidizes glucose. After you place a drop of blood on the test strip, the enzyme reacts with the glucose in the blood, producing an electrical signal on the meter. The higher the strength of the signal, higher is the level of glucose.
