Glucose Screen For Gestational Diabetes
What is a glucose screen for gestational diabetes?
A glucose screen for gestational diabetes is a blood test to find out if you have diabetes caused by pregnancy.
Why do I need a glucose screen?
High blood sugar levels can be harmful to you and to your unborn baby. You may need more tests until your baby is born if your glucose screen shows you have gestational diabetes. Healthcare providers will help you create meal and exercise plans to keep your blood sugar level stable.
When is the glucose screen done?
The test is usually done between 24 and 28 weeks of pregnancy. You may be tested during your first prenatal visit if you have an increased risk of diabetes. Your risk is increased if you have a family member with diabetes. You are also at higher risk if you gave birth to a large baby or you have glucose in your urine.
How is the test done?
- You will fast for as many hours as your healthcare provider directs.
- A sample of your blood will be tested for the amount of sugar it contains.
- Your healthcare provider will give you a sugary drink.
- Your blood will be tested 30 minutes, 1 hour, and 2 hours after you finish the glucose drink. Your healthcare provider may order more tests at 3 or 4 hours after the drink. During this time, you cannot eat or drink anything other than water.
- Your healthcare provider will review your test results to see if your blood sugar levels rose over time.
- You may need the test again 6 to 12 weeks after your baby is born. The test will check that your blood sugar level returned to normal.
