Metabolic tests show how your body handles fuel. Hemoglobin A1c, fasting glucose, fasting insulin and C-peptide together describe blood sugar control and insulin sensitivity long before a single glucose reading changes, and the comprehensive metabolic panel adds electrolytes, kidney and liver values in one draw. These are the tests people order to track a nutrition change, a weight-loss or muscle-gain phase, a family history of diabetes, or a ketogenic diet. Most require an overnight fast.

Reflects endogenous insulin production and pancreatic beta-cell function, useful for evaluating insulin secretion and insulin resistance.
Assesses kidney function, liver enzymes, electrolytes, glucose, calcium, and protein status, providing a broad overview of metabolic, renal, and hepatic health.
Reflects average blood glucose levels over the prior 2–3 months and is used to assess glycemic control and diabetes risk.
Measures fasting insulin levels to assess insulin sensitivity, metabolic health, and early cardiometabolic risk.
Pancreatic enzyme measured to evaluate pancreatic inflammation, injury, or acute pancreatitis.
