Calculator
How it works and when to use it
Matthews: HOMA-IR = fasting glucose (mmol/L) × fasting insulin (µU/mL) ÷ 22.5, or fasting glucose in mg/dL × insulin ÷ 405.
It is used in research and sometimes in the clinic to estimate insulin resistance, there is no single agreed cut-off for every group, so the calculator gives the number for the doctor to read.
Reference: Matthews DR et al. Diabetologia 1985;28:412-9: HOMA-IR = glucose (mmol/L) × insulin (µU/mL) / 22.5 (= glucose mg/dL × insulin / 405)
Frequently asked questions
Is diabetes diagnosed with HOMA-IR?
No, diabetes is diagnosed by fasting glucose, HbA1c or a glucose tolerance test, HOMA-IR only estimates insulin resistance.
Can it be used on insulin treatment?
No, injected insulin changes the measured insulin, so the result means little.
