How to Test Your Blood Sugar With Diabetes
When Should I Test My Blood Sugar? continued...
For people who take multiple insulin injections daily or who use an insulin pump, experts recommend checking the blood sugar level several times a day. Suggested times may include before meals, before exercise, at bedtime, before tasks like driving, as well as when low blood sugar levels are suspected.
Frequency and timing of blood sugar measurements should be individualized. Your health care provider will tell you when and how often you should check your blood sugar.
Note: Acute or chronic illnesses or changes in medications may affect your blood sugar level. You may need to test your blood sugar more frequently when you are ill.
Conditions That Affect Your Blood Sugar
Certain conditions may interfere with an accurate reading of blood sugar and include:
- High air temperature
If you are consistently seeing abnormal results, recalibrate your meter and check the 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.

Monitoring your HbA1c level is also important for diabetes control. Many home glucose monitors have the capacity to 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 draw up 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 help alert you to any problems or trends. Also, these test records help your health care provider make any needed changes in your meal plan, medicine, or exercise program. Bring these records with you every time you visit your health care provider.
