What this test is
The fasting insulin test is a blood test that quantifies the amount of insulin circulating in your bloodstream after an overnight fast. Insulin is a hormone made by the pancreas that helps move glucose from your blood into your cells for energy. This test is typically ordered with a fasting glucose test to give a more complete picture of glucose metabolism.
What it measures
- Fasting insulin — Reflects the amount of insulin in the blood after an overnight fast
What the test involves
The test involves a standard blood draw, usually from a vein in your arm, performed at a laboratory or collection site. You will be asked to fast for a certain number of hours before the sample is taken, as instructed by the lab.
Why it is often ordered
A clinician may order a fasting insulin test to help evaluate possible insulin resistance, hypoglycemia, or other conditions related to how your body regulates blood sugar. It is often used along with other tests to assess overall metabolic health.
Preparation
You will typically need to fast for several hours before the blood draw, and you should follow the specific instructions provided by the collection lab. This may include avoiding food and certain drinks, but water is usually allowed.
How results are reported
Results are reported as a numerical value for insulin concentration in the blood, and the lab will provide a reference range for comparison. Reference ranges can vary between laboratories, so your result should be interpreted in the context of the range provided by the testing lab.
