How and When to Test Your Blood Sugar With Diabetes – Part 2

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
My suggestion is 75 to 105 mg/dl
After meals Less than 180 mg/dl
My suggestion is no more than 140 mg/dl

The above chart is the ADA chart before the latest guidelines. My suggestions are the numbers I am comfortable seeing. This is where you will need your own goals based on your tolerances. These will also vary depending on your age and abilities. Your doctor may also advise different numbers.

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.

Many doctors order certain ranges for your blood glucose, but you need to decide what you are willing to tolerate and set your goals accordingly. Do talk to your doctor if you question his orders. Do this politely and ask if you can make changes if you are uncomfortable with his or her orders.

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.

Yes, keep the records! Many meters are capable of doing ketone tests, so make inquiries about this. Your records are important to find trends or problems. Discuss the changes the doctor wishes to make to your food plan, medicine, or exercise regimen. The doctor may have some good suggestions.

Do listen to the doctor, but don't let the doctor alter your goals unless you agree with what he/she has to say. He may set some short-term goals that could be better for you.

Bob, the CDE instructed me to test between 1-2 hours after eating. Which I did for 3 years. I finally met with an endocrinologist who said to only test 2 hours after eating, not before. She alluded to the situation that other people may need to test sooner, but given my overall numbers and health it was not a good indicator to test an hour after eating.

I'd like to hear your thoughts. Or is that coming up in your next post? Thanks! Jane

Yes, both could be right and most likely they are wrong.


Read this and if you have the test strips this should give you a better idea of how your body processes glucose.

After reading some of the links provided, you will need to decide what works for you. My best time has varied over the years. My experiments started me at 90 minutes, but I have been as long as 140 minutes to as short as 65 minutes.

There is not a one-size-fits-all answer and I have quit experimenting and test anytime between 90 and 120 minutes.

Yes, all the exploration was good and suggested different times, but mostly in the 90 to 120 range. Only one time was I below 90 minutes. Others have different results.
