Glucose Postprandial (2 Hours Post Meals) Test
The GLUCOSE POSTPRANDIAL test is done to see how your body responds to glucose (sugar) after you eat a meal. Within 20 minutes of consuming a meal, insulin rises to its peak level. To normalize the level, insulin moves the glucose into the cells. Within two hours of eating, your insulin and blood glucose levels should return to normal. The test is conducted to measure glucose level post meal.
Why is the test performed?
The postprandial blood glucose test is performed two hours after having food, to see the body’s response to a glucose post – meal. This test is not used to diagnose diabetes.
How to prepare for the test?
The person availing the test should consume the meal exactly 2 hours before the blood sample is taken. After the meal, don’t eat anything else before having the test. Abstain from physical activities of all sorts during the two-hour waiting period as it may increase blood sugar level. Therefore, it is better to be at rest during the waiting period. Also, inform the doctor about all the medicines and supplements one is taking, before the test.
