    What Is a Glucose Challenge Test (75 g) - 1 hour Test?

    The Glucose Challenge Test (GCT) is a quick and easy test that helps doctors determine how well your body manages sugar. It is particularly valuable for identifying gestational diabetes, a form of diabetes that can occur during pregnancy. The test is simple to perform, requires no fasting, and only takes about an hour.

    For this test, you will drink a solution containing 75 grams of sugar dissolved in water. After an hour, a blood sample is collected to measure your blood sugar level. If the level is elevated, it may indicate that your body is not processing sugar correctly, which could suggest gestational diabetes or an increased risk of developing diabetes later in life.

    Doctors usually recommend the GCT between 24 and 28 weeks of pregnancy for all expectant women. If your blood sugar exceeds a specific limit (7.8 mmol/L or more), a follow-up test, the Oral Glucose Tolerance Test (OGTT), may be necessary to confirm diabetes. The OGTT involves drinking a higher amount of sugar (75 or 100 grams) and having your blood sugar measured over a few hours.

    Because the GCT is faster, doesn’t require fasting, and is easier to tolerate, it is more convenient than the OGTT and helps detect potential problems early, thus preventing complications for both mother and baby.

    For those in Hyderabad, the Glucose Challenge Test (75 g) - 1 hour can be performed at home with prompt sample collection and quick result delivery.

    Glucose Challenge Test (75 g) - 1 hour Test Parameters

    This test measures one key factor: the level of glucose in the blood one hour after consuming a solution containing 75 grams of glucose.

    Glucose is the main form of energy used by the body, originating from the carbohydrates found in food and drinks. Once glucose enters your bloodstream, it is transported to your cells for energy. The body also stores excess glucose as glycogen in the liver and muscles for later use. Insulin, a hormone made by the pancreas, is essential for controlling glucose levels. If your body struggles to regulate glucose properly, it can result in high blood sugar (hyperglycaemia) or low blood sugar (hypoglycaemia).

    The GCT helps detect early issues with glucose processing, preventing future health problems.

    The GCT also acts as a test of beta-cell compensation, which refers to how the pancreas produces insulin as the body becomes more resistant to insulin during later pregnancy stages. If the test shows elevated blood sugar, it may mean the pancreas is not working effectively, potentially leading to type 2 diabetes after pregnancy. This test is important for assessing the risk of developing diabetes in the future, particularly for women who have had gestational diabetes.

    • Best Time to Get Tested The Glucose Challenge Test (75 g) - 1-hour test can be taken at any time throughout the day.

    • Who Should Get a Glucose Challenge Test (75 g) - 1 Hour Test? The Glucose Challenge Test (75 g) should be taken by pregnant women, particularly those at risk for gestational diabetes, to detect high blood sugar early and avoid potential complications.

    Why Take the Glucose Challenge Test (75 g) - 1 hour Test?

    The Glucose Challenge Test (GCT) is an essential screening test for detecting diabetes during pregnancy, and it serves the following purposes:

    • Early Detection of Gestational Diabetes – The GCT helps identify high blood sugar levels early in pregnancy, preventing potential complications.

    • Predicts Future Health Risks – This test is not only crucial for detecting gestational diabetes but also serves as an early indicator of future health risks such as high blood sugar, cholesterol problems, and heart disease in women.

    • Identifies Hidden Cardiovascular Risks – Abnormal results from the GCT may indicate a higher risk of elevated fasting glucose, increased cholesterol levels, and metabolic disturbances, raising the likelihood of type 2 diabetes later in life.

    • Guides Further Testing – If the glucose levels exceed the normal threshold (usually ≥7.8 mmol/L), a follow-up Oral Glucose Tolerance Test (OGTT) is recommended to confirm gestational diabetes.

    The Glucose Challenge Test is a vital step in ensuring a healthy pregnancy and long-term well-being for both mother and baby.
