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

    The Glucose Challenge Test (GCT) is a quick and simple test that helps doctors evaluate how effectively your body handles sugar. It is especially helpful for detecting gestational diabetes, a condition that can develop during pregnancy. This test is easy to perform, doesn’t require fasting, and can be completed in just one hour.

    During the test, you will drink a solution containing 75 grams of sugar mixed in water. After an hour, your blood will be drawn to check your blood sugar levels. If your blood sugar is elevated, it could indicate that your body is struggling to process sugar properly, potentially pointing to gestational diabetes or an increased risk of future diabetes.

    Doctors typically recommend the GCT between 24 and 28 weeks of pregnancy for all pregnant women. If your blood sugar exceeds a certain threshold (7.8 mmol/L or more), you may need a follow-up test called the Oral Glucose Tolerance Test (OGTT), which confirms the presence of diabetes. The OGTT involves consuming a higher amount of sugar (75 or 100 grams) and having your blood sugar tested over several hours.

    The GCT is quicker, doesn't require fasting, and is easier to tolerate, making it more convenient than the OGTT. It also helps detect potential issues early, preventing complications for both mother and baby.

    For people living in Mumbai, the Glucose Challenge Test (75 g) - 1 hour can be done at home with fast sample collection and results delivered quickly.

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

    This test measures a single parameter: the glucose level in your blood one hour after drinking a solution that contains 75 grams of glucose.

    Glucose serves as the body's main energy source, coming from the carbohydrates you consume. After glucose enters the bloodstream, it is carried to cells where it is used for energy. The body also stores any excess glucose as glycogen in the liver and muscles for later use. Insulin, a hormone produced by the pancreas, helps regulate glucose levels in the blood. If your body struggles to process glucose correctly, it can lead to hyperglycaemia (high blood sugar) or hypoglycaemia (low blood sugar). The

    GCT is useful for detecting glucose processing issues early, helping to prevent potential health problems in the future.

    The GCT serves as a test for beta-cell compensation, which evaluates how well the pancreas produces insulin as the body becomes more resistant to it later in pregnancy. If the test shows high blood sugar levels, it may suggest that the pancreas is not functioning effectively, which could result in type 2 diabetes after pregnancy. This test is key in predicting future diabetes risk, especially for women who have had gestational diabetes.

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

    The Glucose Challenge test (GCT) is a valuable tool for detecting diabetes during pregnancy, with the following benefits:

    • Early Detection of Gestational Diabetes – The GCT helps detect high blood sugar levels early in pregnancy, preventing complications before they occur.

    • Predicts Future Health Risks – The test not only identifies gestational diabetes but also acts as an early indicator of future health problems, such as high blood sugar, cholesterol issues, and an increased risk of heart disease in women.

    • Identifies Hidden Cardiovascular Risks – Abnormal GCT results may signal higher risks of elevated fasting glucose, increased cholesterol, and metabolic disturbances, all of which can contribute to the development of type 2 diabetes in the future.

    • Guides Further Testing – If glucose levels exceed the normal range (typically ≥7.8 mmol/L), an Oral Glucose Tolerance Test (OGTT) is advised to confirm gestational diabetes.

    The Glucose Challenge test plays a crucial role in ensuring a healthy pregnancy and protecting long-term health for both the mother and baby.
