How and When to Test Your Blood Sugar With Diabetes

What Affects Your Results continued...

If you keep seeing unusual results, recalibrate your meter and check the test strips.

The chart below gives you an idea of where your blood sugar level should be throughout the day. Your ideal blood sugar range may be different from another person's and will change throughout the day.

Time of Test Ideal for Adults With Diabetes
Before meals 70-130 mg/dL
After meals Less than 180 mg/dL

Home Blood Glucose Monitoring and HbA1c

Monitoring your HbA1c level is also important for diabetes control. Many home glucose monitors can display an average blood glucose reading, which correlates with the HbA1c.

When Should I Call My Doctor About My Blood Sugar?

Ask your doctor about your target blood sugar range, and make a plan for how to handle blood sugar readings that are either too high or too low and when to call your doctor. Learn about the symptoms of high or low blood sugar, and know what you can do if you begin to have symptoms.

How Do I Record My Blood Sugar Test Results?

Keep good records of any blood, urine, or ketone tests you do. Most glucose monitors also have a memory. Your records can alert you to any problems or trends. These test records help your doctor make any needed changes in your meal plan, medicine, or exercise program. Bring these records with you every time you see your doctor.
