Why is this test done
The Fasting Insulin Test is performed:
1. To help determine the cause of low blood sugar (hypoglycaemia)
2. To determine the proper production of insulin by the pancreas
3. To determine if insulin resistance in cells is the cause of hyperglycaemia (high blood sugar)
4. To determine if insulin supplementation is necessary
5. To determine the presence of insulin-producing tumors (insulinomas) in the beta cells of the pancreas
What does it measure
This test measures the amount of insulin present in the blood after 8-10 hours of fasting.
What to expect during the test
A blood sample is obtained by inserting a needle into a vein in the arm.
We offer both home collection and the option to visit us at our centres.
Once your sample is collected, it is sent to our laboratories to run the tests.
