What is the Origin of Oral Glucose Tolerance Test?

The test originated from the need for a standardized method to quantify glucose dysregulation, with its clinical application gaining widespread acceptance in the mid-20th century. The term is descriptive, combining "oral," referring to the route of administration, "glucose tolerance," referring to the body's capacity to handle the sugar load, and "test," denoting the diagnostic procedure.

What is the Mechanism of Oral Glucose Tolerance Test?

The test mechanism relies on the physiological response to a significant glucose challenge. Upon ingesting the glucose solution, a healthy pancreas secretes insulin, which promotes the uptake of glucose by muscle and fat cells, rapidly lowering blood glucose levels. In individuals with impaired glucose tolerance or diabetes, the pancreatic beta cells may secrete insufficient insulin, or the peripheral tissues may exhibit insulin resistance, resulting in a prolonged and excessive elevation of plasma glucose levels.

Oral Glucose Tolerance Test

Meaning

The Oral Glucose Tolerance Test (OGTT) is a standardized clinical diagnostic procedure used to assess an individual’s ability to metabolize and clear a specific, measured load of glucose from the bloodstream. This test is crucial for diagnosing prediabetes, gestational diabetes, and type 2 diabetes by measuring plasma glucose levels at baseline and at timed intervals following the ingestion of a glucose solution. It provides a dynamic measure of insulin secretion and peripheral insulin sensitivity.
