What is the Origin of Euglycemic Hyperinsulinemic Clamp?

This technique was pioneered in the 1970s by researchers to provide a standardized, reproducible method for assessing insulin action, overcoming the limitations of less dynamic tests. The name describes the controlled physiological state achieved: euglycemic (normal glucose) and hyperinsulinemic (high insulin), effectively clamping these two variables. It remains the gold standard for metabolic research.

What is the Mechanism of Euglycemic Hyperinsulinemic Clamp?

The high insulin infusion maximizes insulin binding to receptors on peripheral tissues, primarily skeletal muscle and adipose tissue, stimulating glucose uptake. By measuring the glucose infusion rate needed to prevent hypoglycemia, clinicians quantify the amount of glucose being cleared from the blood by the action of insulin. A higher glucose infusion rate indicates greater insulin sensitivity, reflecting efficient glucose disposal and metabolic health.

Euglycemic Hyperinsulinemic Clamp

Meaning

The Euglycemic Hyperinsulinemic Clamp is a precise and definitive research technique used in endocrinology to quantify an individual’s whole-body insulin sensitivity. During the procedure, insulin is infused at a constant, high rate to achieve hyperinsulinemia, while glucose is simultaneously infused and adjusted to maintain blood glucose levels within the normal, euglycemic range. The rate of glucose infusion required to maintain euglycemia serves as the direct measure of insulin sensitivity.
