The Fasting Insulin test measures the level of insulin in your blood after an overnight fast. Insulin is a hormone that regulates blood sugar levels and plays a critical role in metabolism. Abnormal fasting insulin levels can indicate insulin resistance, which is a precursor to type 2 diabetes and metabolic syndrome. This test is important for understanding how well your body manages glucose and can help inform dietary and lifestyle changes to improve your metabolic health.
