What Is Included?
The FIRI profile includes a core triad of metabolic markers to calculate your exact insulin sensitivity.
Fasting Glucose
Measures your baseline blood sugar levels after an overnight fast, which is crucial for evaluating fundamental glucose metabolism and screening for prediabetes.
Detecting elevated resting blood sugars before significant pancreatic strain occurs.
Fasting Insulin
Assesses the resting level of insulin, the hormone produced by the pancreas that regulates and drives blood sugar into your body’s cells for energy.
Identifying hyperinsulinemia (overproduction of insulin to compensate for cellular resistance).
FIRI Calculation
Uses your exact glucose and insulin levels to calculate the Fasting Insulin Resistance Index, which mathematically indicates how effectively your body uses insulin.
Providing a concrete metric to diagnose early-stage insulin resistance and metabolic syndrome.
The Key Benefits of FIRI
The Fasting Insulin Resistance Index (FIRI) profile offers a comprehensive evaluation of insulin sensitivity and glucose metabolism. By providing crucial information about insulin resistance, this profile supports early detection and management of metabolic disorders, enabling timely intervention and improved health outcomes long before type 2 diabetes fully develops.
Your Appointment Day: Fasting Required
Important: For accurate results, fasting for at least 8-12 hours before the test is absolutely required. This ensures that glucose and insulin levels are measured accurately without the influence of recent food intake. You may drink plain water.
Upon arrival at Medical Diagnosis Victoria, a qualified phlebotomist will take a small blood sample from your arm. The process is simple and takes only a few minutes. Booking a morning slot online ensures priority service while fasting.

How To Read Your Laboratory Results
Your results will list your values alongside standard reference ranges. If a result falls outside the range, it is noted for review. Important: A single out-of-range value does not automatically indicate a medical problem. Results must be assessed in conjunction with your medical history and clinical examination.
Results Timeline: FIRI profile metrics are processed rapidly and are typically available within just 4 hours. Once your results are ready, they will be securely shared with you.
