2 Hour Glucose Post Prandial

Why is it done

The goal of glucose testing is to determine whether a patient has an impaired response to glucose resulting in elevated blood glucose concentrations. To determine if your blood glucose level is within healthy ranges; to screen for, diagnose, and monitor hyperglycemia, hypoglycemia, diabetes, and pre-diabetes

Test Overview

Postprandial glucose levels may be abnormally high in patients with gestational diabetes. If results are positive, and the patient is pregnant, a 3-hour oral glucose tolerance test should be performed for confirmation of gestational diabetes.
Glucose is a simple sugar that serves as the main source of energy for the body. The carbohydrates we eat are broken down into glucose (and a few other simple sugars), absorbed by the small intestine, and circulated throughout the body. Most of the body's cells require glucose for energy production; brain and nervous system cells not only rely on glucose for energy, they can only function when glucose levels in the blood remain above a certain level.
