A postprandial glucose test is a blood glucose test that determines the amount of a type of sugar, called glucose, in the blood after a meal. Glucose comes from carbohydrate foods. It is the main source of energy used by the body. Normally, blood glucose levels increase slightly after eating. This increase causes the pancreas to release insulin, which assists the body in removing glucose from the blood and storing it for energy. People with diabetes may not produce or respond properly to insulin, which causes their blood glucose to remain elevated. Blood glucose levels that remain high over time can damage the eyes, kidneys, nerves, and blood vessels. A 2-hour postprandial blood glucose test ("2 hour p.c. blood glucose test", etc.) measures blood glucose exactly 2 hours after eating a meal,〔 (WebMD )〕 timed from the start of the meal. 〔 () 〕 By this point blood sugar has usually gone back down in healthy people, but it may still be elevated in people with diabetes. Thus, it serves as a test of whether a person may have diabetes, or of whether a person who has diabetes is successfully controlling their blood sugar. ==Purpose== Blood glucose tests are done to: * Check for and monitor the treatment of diabetes.〔 * Check for diabetes that occurs during pregnancy gestational diabetes.〔 * Determine if an abnormally low blood sugar level hypoglycemia is present.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Postprandial glucose test」の詳細全文を読む スポンサード リンク
