Why do I have to test my blood sugar?

Testing your blood sugar is the best way to find out how well your diabetes is controlled. A log book of your blood sugar levels will help you see how food, physical activity, and diabetes medicines affect your blood sugar. If your blood sugar is too low or too high, your health care provider might want to adjust your diet, exercise, or the amount of medicine you are taking. Take your log book with you whenever you visit your health care provider.

When should I test my blood sugar?

The most common times to test your blood sugar level are before meals and at bedtime. Your health care provider will tell you how often and when to check your blood sugar.

What tests do I need to do at home?

  • Blood test: The blood test is used to measure the amount of sugar in your blood. It will help you find out if your meal plan, exercise, and medicine are working to control your blood sugar.
  • Urine test: The urine test looks for ketones in your urine. This can be done if you are sick or if your blood sugar level is very high. Meters are also available that can test your blood for ketones.
