GTT Test (Glucose Tolerance Test): Procedure, Full Form, Normal Values & Pregnancy Range The human body manages sugar levels with remarkable precision.

What Is the Full Form and Purpose of the GTT? The gtt test full form is the Glucose Tolerance Test. It measures how quickly your body clears sugar from the bloodstream after you consume a specific dose. This test is different from a simple fasting sugar check.

This is essentially the same procedure where you drink a sweet solution to challenge your system. Doctors use this data to identify prediabetes as well as gestational diabetes.
Why Do Doctors Recommend Specific GTT Indications? A physician often suggests this test based on your risk factors or current symptoms. The indications of GTT include persistent fatigue or unexplained weight changes. High-risk individuals, such as those with a family history of diabetes, often undergo this screen. The glucose tolerance test indications are also very specific for expectant mothers. A failure to process sugar correctly during pregnancy can affect both the mother and the baby. Some people confuse this with the glucose challenge test (GCT). The difference between GTT and GCT lies in the duration and the number of blood draws involved. The GTT is more comprehensive comparatively.

a baseline blood sample to check your fasting levels. You must then consume a sugary beverage within a few minutes. The glucose tolerance test procedure involves a series of steps: ● ● ● ●
