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[edit | edit source]
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[edit | edit source]
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[edit | edit source]
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.
