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

    The Glucose Challenge Test (GCT) is a fast and simple test that helps doctors evaluate how your body processes sugar. It is particularly useful for diagnosing gestational diabetes, a form of diabetes that can occur during pregnancy. This test is easy to perform, doesn't require fasting, and takes only an hour to complete.

    In the test, you will drink a solution containing 75 grams of sugar dissolved in water. After one hour, a blood sample will be taken to measure your blood sugar level. If your blood sugar is elevated, it may suggest that your body is struggling to process sugar, which could indicate gestational diabetes or a heightened risk of future diabetes.

    The GCT is typically recommended between 24 and 28 weeks of pregnancy for all women. If your blood sugar exceeds a set level (7.8 mmol/L or higher), you may need to undergo a follow-up test called the Oral Glucose Tolerance Test (OGTT) to confirm whether diabetes is present. The OGTT requires drinking a higher dose of sugar (usually 75 or 100 grams) and having your blood sugar monitored over a few hours.

    Because the GCT is quicker, doesn't require fasting, and is easier to tolerate, it offers more convenience than the OGTT and helps detect potential issues early, reducing risks for both mother and baby.

    For individuals in Delhi, the Glucose Challenge Test (75 g) - 1 hour at home can be conveniently conducted with a quick sample collection and results delivered promptly.

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

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

    Glucose is the body's primary source of energy, derived from the carbohydrates in your diet. Once glucose enters your bloodstream, it is transported to the cells where it is used for energy. The body also stores excess glucose as glycogen in the muscles and liver for later use. Insulin, a hormone produced by the pancreas, regulates blood glucose levels. If your body has trouble processing glucose, it may lead to high blood sugar (hyperglycaemia) or low blood sugar (hypoglycaemia). The GCT can identify early signs of glucose processing issues, preventing future health concerns.

    The GCT also tests the pancreas's beta-cell compensation, which refers to the ability of the pancreas to produce insulin as the body becomes more resistant to insulin during later pregnancy stages. Elevated blood sugar levels in this test could indicate the pancreas is not functioning well, potentially leading to type 2 diabetes after pregnancy. This test plays a vital role in predicting the risk of developing diabetes, particularly for women with a history of gestational diabetes.

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

    The Glucose Challenge Test (GCT) is an important screening tool for detecting diabetes during pregnancy, and it has the following uses:

    • Early Detection of Gestational Diabetes – The GCT is effective in identifying high blood sugar during pregnancy, preventing complications before they occur.

    • Predicts Future Health Risks – Not only does the test help detect gestational diabetes, but it also serves as an early warning system for potential future health issues, including high blood sugar, cholesterol imbalances, and heart disease in women.

    • Identifies Hidden Cardiovascular Risks – Women with abnormal GCT results might face higher fasting glucose levels, elevated cholesterol, and metabolic disturbances, putting them at greater risk for type 2 diabetes later in life.

    • Guides Further Testing – If the glucose level is above the normal range (usually ≥7.8 mmol/L), an Oral Glucose Tolerance Test (OGTT) is recommended to confirm the diagnosis of gestational diabetes.

    The Glucose Challenge Test is essential for ensuring both a safe pregnancy and long-term health for the mother and baby.
