Fasting Insulin Test

The Fasting Insulin Test is used to measure the amount of insulin in your blood after a period of not eating. It is exceptionally helpful for identifying insulin resistance, a condition where your body cells do not respond well to the hormone, often serving as an early warning sign for Type 2 diabetes before blood sugar levels even begin to spike. Beyond diabetes screening, this test helps clinicians investigate the causes of hypoglycaemia (low blood sugar), monitor the effectiveness of treatment for metabolic syndrome, and check for the presence of insulin-producing tumors known as insulinomas. By providing a clear picture of how your pancreas is functioning, it allows for proactive lifestyle or medical interventions to maintain long-term metabolic health.
