The full form of GTT is the Glucose Tolerance Test, which is used to measure the human body’s ability to handle glucose, which is a kind of sugar available in fruits and bread. It is a universally accepted test to diagnose prediabetes and diabetes.
The medical practitioner asks the patient to consume a glucose solution during the Glucose Tolerance Test. Till the next 3 hours of drinking this glucose-laden liquid, the healthcare professional checks the blood sugar level in the patient’s body every hour.
Background of GTT
GTT was first used in 1923 by Dr Charles Best and Dr Frederick Banting. They innovated this diagnostic exam when they were engaged in working on the seclusion of insulin from the pancreas. During their study, they deciphered that they can detect blood sugar levels by orally administering glucose solution to the human body.
Use of GTT
Along with the full form of GTT, we must also learn about the usage of the Glucose Tolerance Test to expand our knowledge:
- Diagnosis of prediabetes, gestational diabetes, and diabetes mellitus
- Prognosis of Crushing’s syndrome and polycystic ovary syndrome (PCOS)
- Minor treatment of diabetic conditions

The benefits of GTT are as follows:
