Glucose Tolerance Test (GTT 2 Hr)

Overview:
The Glucose Tolerance Test (GTT 2 Hr.) is a diagnostic test used to evaluate how well the body processes glucose. This test is commonly used to diagnose diabetes, prediabetes, and gestational diabetes. During the test, the individual consumes a glucose solution, and blood sugar levels are measured over a two-hour period.

What it detects:
The GTT 2 Hr. detects how effectively the body responds to glucose over a two-hour period. It helps to identify impaired glucose tolerance (prediabetes), diabetes, or gestational diabetes based on how blood glucose levels rise and fall during the test.

Who should get it:
Individuals who are at risk for diabetes or those who show symptoms such as increased thirst, frequent urination, unexplained weight loss, or fatigue may need this test. It is also used to diagnose gestational diabetes in pregnant women, particularly if they have risk factors like obesity or a family history of diabetes.

Sample required:
A blood sample is required, with multiple samples taken over the two-hour period after consuming a glucose drink.

Fasting requirements:
Fasting is required before the test, typically for 8-12 hours.

Processing time:
Results available on Same Day.
