Glucose, Two-hour Postprandial
A blood glucose test measures the amount of a type of sugar, called glucose, in your blood. Glucose comes from eating carbohydrates in food and is the main source of energy used by the body.
Normally, your blood glucose levels increase slightly after you eat. This increase causes your pancreas to release insulin so that your blood glucose levels do not get too high. Blood glucose levels that remain high over time can damage your eyes, kidneys, nerves, and blood vessels.
