Oral glucose tolerance test

Oral Glucose Tolerance Test

The Oral Glucose Tolerance Test (OGTT) is a medical test used to diagnose prediabetes and diabetes. The test measures the body's ability to use glucose, which is the body's main source of energy.

Procedure

The OGTT involves fasting overnight, then drinking a solution containing a certain amount of glucose. Blood samples are taken before the test, and at intervals for up to three hours afterwards, to measure the glucose levels in the blood.

Interpretation

The results of the OGTT are interpreted based on the glucose levels in the blood at different times during the test. A higher than normal glucose level may indicate prediabetes or diabetes.

Risks and Complications

While the OGTT is generally safe, there are some risks and potential complications. These include nausea, vomiting, and fainting. There is also a small risk of developing a bruise or infection at the site where the blood is drawn.
