Post Prandial Blood Sugar Test or Post Lunch Blood Sugar
A postprandial glucose test / plbs 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. Insulin, secreted by the pancreas controls the amount of Glucose in the blood.
A 2-hour postprandial blood glucose test measures level of glucose in blood exactly 2 hours after eating a meal, timed from the start of the meal. 2 hours after a meal, 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.
