What is the full form of GTT?

The full form of GTT is 'Glucose Tolerance Test.' This medical test measures how effectively the body processes glucose. It's commonly used to diagnose diabetes, including gestational diabetes during pregnancy. The test involves measuring blood sugar levels after fasting and then again after consuming a glucose-rich drink.

How Is the Glucose Tolerance Test Conducted?

  • The test starts with measuring fasting blood sugar levels.
  • After fasting, the patient consumes a glucose-rich drink.
  • Blood sugar levels are then measured at intervals over a few hours to assess glucose processing efficiency.

Why Is GTT Important During Pregnancy?

  • GTT is crucial for detecting gestational diabetes, which can affect both mother and baby's health.
  • It ensures timely intervention to manage blood sugar levels during pregnancy.

What Are the Different Types of Glucose Tolerance Tests?

  • Oral Glucose Tolerance Test (OGTT) is the standard method.
  • Intravenous Glucose Tolerance Test (IGTT) is used for research purposes and involves glucose infusion into the veins.


The Glucose Tolerance Test, or GTT, is a vital diagnostic tool for identifying diabetes and managing it effectively. It's especially important for monitoring and ensuring the health of pregnant women and their unborn children.
