What Is An Insulin Fasting Test?
Insulin is a hormone produced by the pancreas that helps regulate blood glucose levels by allowing cells to absorb glucose for energy. The insulin fasting test is a blood test that measures the level of insulin in blood after fasting for a specified period, usually overnight to 12 hours. The test is often used to evaluate insulin resistance, a condition where the cells do not respond effectively to insulin, leading to elevated blood sugar levels.
The test is crucial for diagnosing and managing type 2 diabetes, prediabetes and metabolic syndrome. It is also used for monitoring treatments for insulin resistance or diabetes. Measuring fasting insulin levels helps your healthcare provider to assess how well the pancreas is functioning and identify early signs of insulin related disorders. Early detection and intervention can help prevent complications such as cardiovascular disease, kidney damage and nerve damage.
How is the Test Performed?
Insulin fasting test is a blood test.
Preparation
Overnight or up to 12 hours of fasting is required for this test.
Sample Collection
A healthcare professional will draw a small amount of blood from your arm.

What are Normal Ranges for This Test?
For adults the normal range for fasting insulin levels is 2–25 µU/mL. Slight variations may occur due to hormonal fluctuations (e.g. PCOS, pregnancy). The levels may vary in children according to age, consult a pediatrician for optimal ranges.
**The above mentioned range is for information purpose only. Normal levels are dependent on a number of factors including age, gender how the test is performed and health condition of patient etc. Result interpretation should be done by a qualified doctor or healthcare professional.**
What Happens if Test Results Show Abnormal Levels?
High Insulin Levels – May indicate insulin resistance, type 2 diabetes, metabolic syndrome or PCOS. Your doctor may recommend lifestyle modifications, further glucose tests or medications.
Low Insulin Levels – Can indicate type 1 diabetes, pancreatic disorders or severe insulin deficiency. Additional tests, such as glucose tolerance tests or HbA1c, may be needed.
Next Steps – Depending on results, your doctor may suggest dietary changes, physical activity, medication or further diagnostic evaluations.
