Fasting insulin measures how much insulin your pancreas is producing to keep blood sugar in range. Elevated fasting insulin is one of the earliest signs of insulin resistance, often appearing years before glucose or A1c levels become abnormal. This makes it a valuable early-detection tool for Type 2 diabetes risk and metabolic syndrome.
