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.

    When is the glucose test done in pregnancy?

    The pregnancy glucose test, formally known as the oral glucose tolerance test (OGTT), is a blood test that measures your body’s ability to break down sugar (glucose). This test diagnoses gestational diabetes, a type of diabetes (high blood sugar) that develops during pregnancy.

    “The test is usually done around 24–28 weeks of pregnancy,” says Alex Juusela, MD, M.P.H., a maternal-fetal medicine fellow at Detroit Medical Center. “Earlier glucose screening is often performed when a patient has risk factors for undiagnosed pre-gestational diabetes and/or is at high risk for developing early gestational diabetes.”

    Risk factors for gestational diabetes include:

  • Family history of diabetes
  • Being overweight (BMI more than 25)
  • Personal history of gestational diabetes in a prior pregnancy
  • High blood pressure
  • Polycystic ovary syndrome (PCOS)
  • Elevated levels of glucose in the urine
  • “It’s crucial that all women perform a glucose test while pregnant because gestational diabetes frequently has no symptoms,” says Robert S. Wool, M.D., an OB-GYN and the Massachusetts-based Women’s Health Associates’ medical director

  • High birth weight (greater than nine pounds)
  • Higher risk of needing a C-section
  • High blood pressure (preeclampsia)
  • Low blood sugar (hypoglycemia) in the newborn
  • Increased risk for stillbirth
  • Increased risk of baby developing obesity or Type 2 diabetes later in life
