What is the purpose of the OGTT test?

The purpose of the Oral Glucose Tolerance Test (OGTT) is to assess the body’s ability to metabolize glucose and to diagnose conditions such as diabetes or insulin resistance. During this test, the patient ingests a specified amount of glucose, and their blood glucose levels are measured at intervals to evaluate how effectively their body processes the glucose.

This procedure is particularly important for identifying gestational diabetes in pregnant women and for diagnosing type 2 diabetes. The results of the OGTT provide medical professionals with crucial information about how well the body's insulin works and whether the patient may have impaired glucose tolerance.

The other options do not accurately describe the purpose of the OGTT. For instance, while the terms "open gastrointestinal tract test" and "organism growth tolerance test" suggest some form of medical testing, they do not relate to glucose metabolism or the specific aims of the OGTT. "Oral general therapy test" is also unrelated, as it does not focus on glucose tolerance specifically.
