Blood Sugar Monitoring for Gestational Diabetes
As part of taking care of your diabetes, you will need to test your blood sugar. Your blood sugar levels help to decide how to adjust meals, snacks, exercise, and if needed, insulin doses. There are many blood sugar meters on the market today. Your nurse will help you choose a meter which best meets your needs.
When to Test
Your team may suggest that you check before breakfast and either one hour or two hours after each meal.
• Blood sugar is usually lowest before eating.
• Blood sugar is highest in the first 1- 2 hours after eating. Checking after meals helps you to know how a certain food affects your blood sugar.
Discuss with your team what is best for you.

Follow manufacturer’s instructions carefully in order to obtain accurate results. User error is the most common cause for mistakes.
To avoid errors:
1. Wash your hands well with soap and warm water before testing. If using rubbing alcohol or hand gels, be sure to let it dry before testing. If it does not dry, the alcohol will affect the results.
2. Be sure you code your meter. Follow the meter instructions.
3. Always carry test strips in the original vial.
4. Check the expiration date on the strip vial. Do not use the strips if they have expired.
5. Check to be sure you have applied enough blood to the test strip.
6. Clean your meter regularly.
7. Use the control solution (s) to check that the meter is working well.
each time you open a new vial of strips
if the test results do not support how you feel
8. If you need to keep checking your blood sugars after the baby is born, make sure you check your meter results against lab results. Your doctor or nurse can tell you about how to do this if needed.
