What is GLUCOSE TOLERANCE TEST (GTT)?

The Glucose Tolerance Test (GTT) measures how well your body processes sugar over a few hours. It involves drinking a sugary solution after an initial blood draw, followed by several more blood samples. This test helps assess your body's response to glucose.

Why is this test important?

GTT is primarily used to diagnose prediabetes, gestational diabetes, and type 2 diabetes. It provides a more detailed picture of glucose metabolism than a single blood sugar test, especially when fasting glucose levels are normal but diabetes is still suspected.

How to Prepare

You will need to fast for 8-12 hours before the test. You will be asked to drink a specific glucose solution during the test.

Frequently Asked Questions

Do I need to fast before my blood test?▼
It depends on the test. Tests like lipid profile and fasting blood sugar require 10-12 hours of fasting. Tests like CBC, vitamin D, and thyroid do not require fasting. Each test page on our website clearly states the fasting requirements.
