About Glucose Tolerance Test

The Glucose Tolerance Test (GTT) is a laboratory investigation used to assess how the body processes glucose. Blood glucose levels are measured at specified times after the patient consumes a glucose solution according to the prescribed testing protocol.

The test may be used to investigate glucose metabolism and support the assessment of diabetes or gestational diabetes, depending on the patient's clinical circumstances and the protocol requested by the doctor.

Why Is a Glucose Tolerance Test Recommended?

A doctor may recommend a GTT when additional information about glucose regulation is needed. It may be used in the assessment of suspected diabetes, impaired glucose tolerance or gestational diabetes when clinically indicated.

The type of glucose tolerance test and the timing of blood collection depend on the reason for testing and the instructions provided by the treating clinician.

What Does the Test Measure?

The test measures blood glucose levels at specified intervals following glucose intake. Comparing these measurements helps clinicians assess how efficiently the body regulates blood glucose.

• Blood glucose response following a prescribed glucose load.
• Changes in glucose levels during the testing period.
• Results that may support the assessment of glucose intolerance or diabetes.

Interpretation depends on the patient's clinical circumstances, the test protocol and the applicable diagnostic criteria.

How Is the Glucose Tolerance Test Performed?

The procedure generally begins with a blood sample collected according to the prescribed protocol. The patient then drinks a glucose solution, and additional blood samples are collected at specified intervals.

The number and timing of samples depend on the type of GTT requested. The patient must follow the laboratory's instructions throughout the testing period for the results to be interpreted appropriately.

Who May Need a Glucose Tolerance Test?
