Description
An insulin blood test measures the amount of insulin in your blood to help diagnose and monitor conditions related to insulin production.
What it can help diagnose
- Hypoglycemia: Low blood sugar
- Insulin resistance: When cells don't respond well to insulin
- Type 2 diabetes: When blood glucose levels are too high
- Insulinoma: A tumor that secretes insulin
What it can help monitor
- Pancreatic islet cell transplant: How well the transplant is working in people with type 1 diabetes
- Treatment for type 2 diabetes: Whether insulin is needed in addition to oral medications
What it can help determine
- Cause of abnormal insulin production: Whether the body is producing too much or too little insulin
The normal range for insulin levels varies by person and depends on factors like age, gender, and health conditions.
Fasting not required.
