Service Providers for Glucose Tolerance Test
A Glucose Tolerance Test (GTT) evaluates how your body processes glucose and is primarily used to diagnose diabetes or gestational diabetes. Preparation includes fasting for 8-12 hours prior. During the test, a fasting blood sample is taken, followed by drinking a glucose solution. Subsequent blood samples are collected at intervals, typically 30 minutes to 2 hours, to monitor glucose levels over time. The procedure is generally safe, though mild side effects like nausea or lightheadedness may occur. Results showing persistently high glucose levels may indicate diabetes or insulin resistance. Factors such as illness, medications, or inadequate fasting can influence results.
