Normal insulin levels can vary depending on the laboratory and the specific assay used for testing. Typically, fasting insulin levels are measured in microunits per milliliter (μU/mL).
What is the Test?
The Insulin – Fasting Serum test measures the concentration of insulin in the blood when a person has fasted for a certain period, usually overnight. Insulin is a pancreatic hormone that plays an important function in controlling blood sugar (glucose) levels. This test is used to assess insulin sensitivity and to help diagnose conditions such as diabetes and insulin resistance.
Test Procedure:
A healthcare provider will draw a blood sample from a vein in your arm, typically in the morning after an overnight fast. A blood sample is delivered to a laboratory for testing. In the laboratory, the blood sample is processed, and the concentration of insulin is measured using specialized equipment.
When to Take the Test:
The Insulin – Fasting Serum test is typically performed in the morning after an overnight fast. Fasting for at least 8 to 12 hours is common to ensure accurate results. Your healthcare provider will provide specific instructions on when to take the test.
