An insulin random test measures the level of insulin in the blood at a random time, regardless of when you last ate. Insulin is a hormone produced by the pancreas that helps regulate blood sugar levels. This test is often used to assess insulin production and to diagnose conditions such as diabetes and insulin resistance.

How our test process works!
The Insulin (Random) test measures the amount of insulin in your blood at a given time, irrespective of when you last ate. Insulin is a hormone produced by the pancreas that helps regulate blood sugar levels. The test is commonly used to assess insulin production and investigate conditions like insulin resistance, diabetes, or other metabolic disorders.
Risk Assessment
Why it’s done:
- Diabetes diagnosis: Differentiating between Type 1 and Type 2 diabetes.
- Insulin resistance: Evaluating conditions like prediabetes or metabolic syndrome.
- Hypoglycemia: Identifying excessive insulin production or inappropriate insulin use.
- Pancreatic disorders: Identifying tumors like insulinomas.
Conditions associated with abnormal insulin levels:
- High levels:
- Insulin resistance (e.g., Type 2 diabetes, metabolic syndrome)
- Insulinoma (pancreatic tumor)
- Cushing’s syndrome
- Obesity
- Low levels:
- Type 1 diabetes
- Advanced Type 2 diabetes with beta-cell exhaustion
- Pancreatic diseases (e.g., chronic pancreatitis).
- Normal Range
The normal range of insulin levels may vary slightly between laboratories. A typical range is:
- 2–25 µU/mL (micro-units per milliliter)
It is important to interpret values based on lab-specific reference ranges and individual clinical contexts.
Interpretation
- High insulin + normal/high blood glucose: Insulin resistance, prediabetes, or metabolic syndrome.
- High insulin + low blood glucose: Hyperinsulinemia or insulinoma.
- Low insulin + high blood glucose: Type 1 diabetes or advanced Type 2 diabetes.
Sample Type: A blood sample is required for this test, usually collected through a simple blood draw from a vein, often in the arm.
