The OGTT test, also known as the Oral Glucose Tolerance Test, is an important test for diagnosing diabetes, but it is not a routine clinical test and the need for it is based on the doctor’s orders at the hospital you see.
In normal people, blood glucose levels are relatively stable, usually peaking 30 to 60 minutes after eating, and then gradually decreasing, approaching the level before eating about 2 to 3 hours later. However, in patients with diabetes or impaired glucose regulation, blood glucose can still be higher than normal after 2 hours. This is how the OGTT test works, to see if there are abnormalities in glucose metabolism.
