Frequently Asked Questions

What is HOMA-IR used for?

HOMA-IR estimates insulin resistance, a state where the body needs more insulin than usual to control blood sugar, using just fasting insulin and fasting glucose rather than more invasive testing.

Why must the blood samples be fasting?

Both insulin and glucose fluctuate significantly after eating, so the formula requires fasting measurements, generally after at least 8 hours without food, to give a stable and interpretable baseline.

What HOMA-IR value suggests insulin resistance?

Values above roughly 2 are commonly used as a general indicator of insulin resistance, though the precise cutoff varies between populations, labs, and assay methods, so results should be interpreted with that context.

Is this calculator a substitute for medical advice?

No. This is an educational reference implementation of the standard HOMA-IR formula, not a substitute for a physicians clinical assessment.
