The Fasting Insulin test measures the level of insulin in your blood after fasting for at least 8 hours (usually overnight). Insulin is a hormone produced by the pancreas that helps regulate blood sugar levels. This test helps assess how well your body is producing insulin and how effectively it is regulating blood sugar when you haven’t eaten for a while.
Assess Insulin Resistance: Elevated insulin levels can indicate insulin resistance, a condition where your body’s cells don’t respond properly to insulin. This is often an early sign of prediabetes or type 2 diabetes.
Monitor Metabolic Health: This test is essential for individuals with conditions like polycystic ovary syndrome (PCOS), obesity, and metabolic syndrome, where insulin resistance is commonly present.
Evaluate Pancreatic Function: It helps assess the health of the pancreas and its ability to produce insulin, which is critical for controlling blood sugar.
The test is typically done in the morning after you’ve fasted for at least 8 hours. A blood sample is taken to measure the amount of insulin in your bloodstream. Elevated levels of fasting insulin may indicate the presence of insulin resistance, while low levels could point to issues like type 1 diabetes or insulin deficiency.
While ranges may vary by laboratory, normal fasting insulin levels generally fall between 2 to 25 µU/mL. Results outside of this range may indicate underlying health issues:
