The Glucose Tolerance Test (GTT), Two-hour (Oral WHO Protocol), evaluates the body's ability to metabolize glucose by measuring blood glucose levels before and two hours after consuming a standardized glucose solution. It is used to diagnose glucose intolerance, type 2 diabetes, and gestational diabetes in pregnant women. This test is particularly useful for patients with borderline fasting or postprandial glucose levels and in the investigation of conditions like unexplained hyperglycemia, hypertriglyceridemia, and other metabolic abnormalities.
