Glucose Blood Test, Two-hour Postprandial

What is the purpose of this test?

The Glucose Blood Test, Two-hour Postprandial, measures your blood sugar levels exactly two hours after you eat a meal. This test helps doctors understand how well your body manages glucose after eating, which is especially important for diagnosing or monitoring conditions like diabetes and prediabetes. After a meal, blood sugar levels naturally rise, but in healthy individuals, insulin helps bring those levels back down within a certain range. The two-hour postprandial test shows if your body is responding to insulin properly by seeing how much your blood sugar drops two hours after eating.

For this test, you'll be asked to eat a meal or drink a glucose solution containing a specific amount of sugar. After exactly two hours, a blood sample is taken to check how much glucose is still in your bloodstream. If your blood sugar levels remain high after two hours, it may suggest that your body is having difficulty using insulin to manage glucose, which can indicate diabetes or prediabetes. This test gives doctors a clearer picture of how your body handles sugar from food, helping guide treatment and management of blood sugar-related conditions.
