The Insulin Resistance Blood Test is a fasting panel that looks for early changes in blood sugar, insulin and cholesterol before diabetes is established. It includes the Fasting Insulin Resistance Index, HbA1c, glucose and iron, a full lipid profile, and broad haematology and biochemistry. The panel costs £279 plus a £50 blood-draw fee, with results in 1 working day. You can walk in or book online at 117a Harley Street, seven days a week, with no GP referral needed.
Doctors order this panel for adults concerned about insulin resistance or metabolic risk, for example with weight gain around the waist or a family history of type 2 diabetes.
It gives a baseline that can be repeated to track changes over time.
A 10 to 12 hour fast is required. Water is fine.
A raised insulin resistance index can show that the body needs more insulin than usual to keep blood sugar normal.
This result is not a complete diabetes or endocrine assessment and must be considered with symptoms and clinical history.
For a wider check of heart, metabolic and general health, see the health MOTs at Health Screening Clinic.
