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

    The Glucose Challenge Test (GCT) is a simple and quick test that helps doctors check how well your body handles sugar. It is particularly useful for identifying gestational diabetes, a type of diabetes that can develop during pregnancy. This test is easy to perform, does not require you to fast beforehand, and takes just one hour to complete.

    During the test, you will drink a solution that contains 75 grams of sugar dissolved in water. After one hour, a blood sample is taken to measure your blood sugar level. If your blood sugar level is higher than normal, it may indicate that your body is having trouble processing sugar properly, which could mean that you have gestational diabetes or are at a higher risk of developing diabetes in the future.

    Doctors usually recommend the GCT between 24 and 28 weeks of pregnancy for all pregnant women. If your blood sugar level is higher than a specific threshold (7.8 mmol/L or more), you may need to undergo a follow-up test called the Oral Glucose Tolerance Test (OGTT) which confirms presence of diabetes in pregnant individuals. The OGTT involves drinking a higher concentration of sugar (usually 75 grams or 100 grams), and having your blood sugar checked at different points over the next few hours.

    Because the GCT is quicker, requires no fasting, and is easier to tolerate, it is more convenient than the OGTT and also helps to detect issues early and prevent complications for both mother and baby.

    For individuals residing in Bangalore, getting a Glucose Challenge Test (75 g) - 1 hour test at home can be convenient with prompt sample collection and delivery of results.

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

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

    Glucose is the main form of energy that your body uses. It comes from the carbohydrates in the food and drinks you consume. Once glucose enters your blood, it is carried to your cells, where it is used for energy. Your body also stores unused glucose as glycogen in your muscles and liver to use later. Insulin, a hormone made by your pancreas, is essential for controlling glucose levels. If your body struggles to use glucose properly, it can lead to high blood sugar (hyperglycaemia) or low blood sugar (hypoglycaemia). The GCT helps identify problems with glucose processing early, which can prevent future health issues.

    The GCT serves as a test of beta-cell compensation, which refers to the ability of the pancreas to produce insulin as the body becomes more resistant to it during the later stages of pregnancy. If the test shows high blood sugar levels, it might mean the pancreas is not working well, which can lead to type 2 diabetes after pregnancy. This test is important for predicting the risk of diabetes in the future, especially for women who have had gestational diabetes.

    • Early Detection of Gestational Diabetes The GCT helps identify high blood sugar levels during pregnancy before they cause complications.

    • Predicts Future Health Risks – The test not only helps detect gestational diabetes but also serves as an early warning sign of future health problems like high blood sugar, cholesterol issues, and heart disease in women.

    • Identifies Hidden Cardiovascular Risks – Women with abnormal GCT results may have a higher postpartum fasting glucose, increased cholesterol levels, and metabolic disturbances, raising the risk of type 2 diabetes later in life.

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

    The Glucose Challenge Test is a crucial step in ensuring a safe pregnancy and long-term health for both mother and baby.
