Context:

Insulin resistance is a common clinical issue, gaining attention since Reaven's 1988 description of Syndrome X.
Syndrome X (metabolic syndrome) involves high triglycerides, hypertension, low HDL, and insulin resistance, increasing coronary artery disease risk.

Purpose:

To review and compare various methods for measuring insulin resistance.
To highlight the importance of accurate insulin sensitivity assessment in clinical and research settings.

Summary:

The euglycaemic clamp method measures insulin sensitivity by infusing insulin and glucose to maintain constant blood glucose levels, with sensitivity expressed as glucose infusion rate.
Steady-state plasma glucose methods use drugs to suppress insulin secretion, then infuse glucose and insulin at constant rates.

Bergman's minimal model and modified insulin tolerance tests offer alternative, more practical approaches with specific applications.

Impact:

Understanding the advantages and disadvantages of each method (precision, cost, duration) aids in selecting the most appropriate technique.
Accurate measurement of insulin resistance is vital for diagnosing and managing metabolic syndrome and related cardiovascular risks.
