How is a glucose challenge test performed?

• A. A mother ingests 50g of oral glucose solution
• B. A mother undergoes intravenous glucose infusion
• C. A blood sample is taken without prior ingestion
• D. A mother eats a high-carb meal before the test

Answer: (A)

The glucose challenge test is performed by having a mother ingest a specific amount of glucose solution, typically 50 grams. This test is designed to assess how the body processes glucose and is commonly used as a screening tool for gestational diabetes. After the ingestion of glucose, blood samples are taken at set intervals to measure the blood sugar levels.

This method is effective because it allows health care providers to evaluate the mother's ability to handle glucose loads, which is critical for identifying any potential glucose metabolism issues during pregnancy. The ingestion of the glucose solution is key to simulating how the body reacts to sugar, making this approach standard practice in prenatal care.
