What are glucose screening tests during pregnancy?

Gestational diabetes is a common condition during pregnancy that affects up to 10% of pregnant people It indicates that your blood sugar or glucose levels are too high. A glucose screening checks for signs of gestational diabetes. Prenatal care professionals use a glucose test to identify gestational diabetes. Gestational diabetes can be problematic for both you and the fetus if it is not treated.

Your healthcare provider will provide you with a glucose challenge test and a glucose tolerance test while you are pregnant.

The first test is a screening, which is the main distinction. It tells your provider that you may have gestational diabetes. Your doctor may order a second test if the screening results you received are abnormal. The second test diagnoses gestational diabetes. Both tests entail having blood drawn from a vein in your arm and consuming a sweet beverage that contains glucose.

Since the glucose challenge test is a screening, it can identify women who are more likely to develop gestational diabetes. This screening is a routine part of your prenatal care. There is a greater chance that you have gestational diabetes if the results are irregular. However, it doesn’t diagnose gestational diabetes. Numerous names have been coined to describe this initial screening. Some other names are:

  • Glucose screening.
  • Gestational diabetes screening.
  • One-hour glucose challenge test.
  • Despite the fact that terminology varies, it’s crucial to understand that this initial test is a screening If you fail, it doesn’t mean you have gestational diabetes. It denotes that a second test to identify the condition will be advised by your pregnancy care provider. No additional testing is required if your screening results are normal.

    This test diagnoses gestational diabetes. It requires multiple blood draws at predetermined intervals, takes three hours, and You must fast for a longer period of time prior to the test because it is more involved. The three-hour glucose test is another name for the glucose tolerance test.

    How do I prepare for a glucose tolerance test?

    Your prenatal care provider will advise a second test to identify gestational diabetes if your glucose screening is unsuccessful. Similar tests exist, but this one takes longer and necessitates more blood draws.

    Before your test, your healthcare provider will give you specific dietary instructions. The instructions may include:

  • Eating at least 150 milligrams (mg) of carbohydrates per day for three days before testing.
  • Restricting all food and drink for at least eight to 12 hours before the test. Drinking a few sips of water the morning of the test is usually OK.
  • Scheduling your test for first thing in the morning.
  • It’s crucial to remember that you could have a negative glucose screening but a positive glucose tolerance test.
