Fasting Insulin Resistance Index - HOMA IR – Private Testing in London
The Fasting Insulin Resistance Index (HOMA-IR) is available at Wimpole Street Medical and Dental, our clinic in Marylebone, London W1G. This test is priced at £98. A £50 phlebotomy fee applies per visit for blood collection. It requires a venous blood sample taken after an overnight fast, and results are typically available within 1 day.
HOMA-IR is calculated from your fasting glucose and fasting insulin levels and is one of the most widely used non-invasive markers of insulin resistance. A higher HOMA-IR value indicates that your body is producing more insulin to keep blood glucose stable, an early warning sign that may precede pre-diabetes, type 2 diabetes, polycystic ovary syndrome (PCOS) and non-alcoholic fatty liver disease. Your results should be interpreted alongside your symptoms, BMI, lipid profile and HbA1c by a clinician.
Who Should Consider the Fasting Insulin Resistance Index (HOMA-IR)?
This test may be helpful if you have a family history of type 2 diabetes, are overweight or have central (abdominal) obesity, have been told you have pre-diabetes, polycystic ovary syndrome (PCOS), non-alcoholic fatty liver disease (NAFLD/MASLD) or metabolic syndrome, or experience symptoms such as persistent fatigue after meals, sugar cravings, unexplained weight gain or skin changes such as acanthosis nigricans (dark velvety patches at the neck or armpits).
HOMA-IR is also useful for tracking your response to lifestyle changes (diet, exercise, weight loss) or to medication such as metformin or GLP-1 receptor agonists. It is not a diagnostic test on its own, clinical correlation with your full history, examination and other markers (HbA1c, fasting glucose, lipids, liver function) is essential.
A trained nurse collects the blood sample by standard venepuncture, which typically takes around five minutes. Our clinic is on Wimpole Street, a short walk from Bond Street and Oxford Circus stations. No GP referral is needed, book online or call 020 7183 0692.
Insulin Resistance & Metabolic Health
Insulin resistance can develop years before blood glucose becomes abnormal. HOMA-IR helps detect it early so you can act before pre-diabetes or type 2 diabetes develops.
