Mixed Meal Tolerance Test

A physiological dynamic assessment evaluating beta-cell secretory capacity and postprandial glycemic regulation under mixed macronutrient stimulation. Crucial for assessing residual endogenous insulin production via C-peptide in type 1 diabetes intervention trials, evaluating post-bariatric hypoglycemia, and differentiating hyperinsulinemic hypoglycemia etiologies where standard oral glucose fails to replicate native incretin and neural secretagogue responses.
