Glucose Tolerance Test with Insulin (8 specimens) Blood Test
Item # LC100014
Measures four samples of glucose & insulin over 3 hours
This test measures glucose and insulin prior to glucose consumption and every hour thereafter for 3 hours--showing how your body responds after a meal.
Glucose is the primary blood sugar used by cells to make energy. Because glucose is so important to your cells, the body regulates it in many different ways. The one most commonly understood involves insulin, a hormone secreted by the pancreas that delivers glucose to cells throughout the body. When you eat a meal, the pancreas responds by releasing insulin to transport the glucose into the cells. As long as receptors on the cell walls remain sensitive to insulin, the channeling of glucose out of the bloodstream occurs relatively quickly and without excessive insulin production. Sometimes, however, the cells become resistant to insulin’s effects. When this happens, the pancreas pumps out ever-greater amounts of insulin in an attempt to force the glucose into the cells. This effort is only partially effective in most instances, and may result in higher blood glucose levels. Blood glucose levels that remain high over time can damage your eyes, kidneys, nerves, and blood vessels. Your results will typically display one of the following common patterns, which can be useful information in determining how your body responds to consuming glucose: ![]() This test can be used by your doctor to help diagnose diabetes and/or pre-diabetes.
