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 is a glucose screening performed during pregnancy?

    A sweetened beverage called glucola that contains 50 grams (g) of the sugar glucose is consumed within five minutes for a glucose screening test. Your blood is drawn from a vein in your arm 60 minutes (one hour) after ingesting the solution by a phlebotomist. The blood test evaluates how your body utilized the glucose solution. From the time you drink the glucola until the blood draw, you cannot eat or drink anything. Having a few sips of water is usually OK.

    After 60 minutes, a higher-than-normal blood glucose level does not necessarily indicate gestational diabetes. To identify gestational diabetes, your doctor will likely order a second glucose test (glucose tolerance test).
