About this test

What is this test for?

The glucose tolerance test helps identify abnormalities in how the body handles sugar, including impaired glucose tolerance or diabetes. It offers more detailed insight than a single fasting measurement and supports early intervention where necessary.


What does this test measure?

The test evaluates how the body processes glucose over a defined period after consuming a measured glucose solution. Blood samples are taken at specific intervals to observe how quickly glucose levels rise and return toward baseline. This provides dynamic information about insulin response and glucose metabolism.


When is this test recommended?

A glucose tolerance test may be recommended when there is concern about impaired glucose regulation that is not clearly identified through fasting glucose alone. It is often used in the investigation of pre-diabetes, diabetes, or gestational diabetes. Individuals with risk factors such as family history, metabolic syndrome, or unexplained blood sugar fluctuations may be referred for this assessment.
