GTT- Glucose Tolerance Test
Overview
The Glucose Tolerance Test (GTT) is used to diagnose diabetes and insulin resistance. It involves fasting overnight, then drinking a glucose solution. Blood glucose levels are measured at intervals—typically before drinking, and then at 1, 2, and sometimes 3 hours afterward. A normal result shows blood sugar levels returning to baseline within a few hours. Elevated levels at specific times may indicate prediabetes or diabetes. The test helps assess how effectively the body processes glucose. It’s commonly used for diagnosing gestational diabetes in pregnant women and for evaluating persistent high blood sugar levels. Accurate preparation and adherence to testing protocols are crucial for reliable results.
