Why get tested?
To help evaluate insulin production, diagnose an insulinoma (insulin-producing tumour), and to help determine the cause of low blood glucose (hypoglycaemia)

When to get tested?
If you have hypoglycaemia, if you have symptoms suggesting insulin is being inappropriately produced by your body, and sometimes if you have diabetes and your doctor wants to monitor your insulin production

Sample required?
A blood sample drawn from a vein in your arm
