HOMA-IR — What It Means in Your Blood Test
New to reading lab reports? Start with our guide to reading a blood test report
This score estimates how well your cells are listening to insulin, the hormone that manages blood sugar.
HOMA-IR blends two resting blood values into one score about how readily your cells heed insulin. A higher figure suggests they are tuning out that hormone.
Also known as: Homeostatic Model Assessment of Insulin Resistance, HOMA, insulin resistance index, HOMA2-IR
This isn't a case where higher or lower is better. Your body keeps it in a narrow band, and both directions can matter.

What is HOMA-IR?
This score combines your fasting sugar and fasting insulin into a single figure. When cells respond poorly, the pancreas pumps out extra insulin to hold sugar down, and that mismatch pushes the score up.
Why is HOMA-IR tested?
This score estimates insulin resistance from two blood values you may already have, with no extra procedure.
What is a normal HOMA-IR range?
- India
- No India-specific national reference interval is published for this parameter; your lab's printed range is the most reliable comparison.
- Global
- <2.0 often used as a reference cutoff; values vary by population and study methodology
Ranges vary by lab, method and equipment — the range printed on your own report is the one that applies to your result.

What does your HOMA-IR value mean?
There is no widely-accepted set of value bands for this parameter. Compare your result with the reference range printed on your own report, and discuss it with your doctor.
What does a high HOMA-IR result mean?
A higher score suggests your cells may be responding to insulin less well. Your doctor reads it with your weight and other results. It is worth discussing with your doctor.
What does a low HOMA-IR result mean?
A lower score suggests your cells are responding to insulin well. This is generally the more reassuring direction.
What can affect your HOMA-IR result?
- whether you had fasted
- your weight
- where you carry fat
- some medicines
- a sudden illness
In the Indian context
Indian studies such as ICMR-INDIAB have found that insulin resistance often appears at a lower body weight in Indians than in many other groups [ICMR].
Questions to ask your doctor
About this result
- What does my HOMA-IR score suggest about how well my cells are responding to insulin?
- Given how common insulin resistance is in Indians even at a lower weight, is my score a concern for me?
What to do next
- Would changes to my diet, activity or waist size be likely to improve my HOMA-IR?
- Should my HOMA-IR be looked at together with my fasting sugar, weight and lipid results?
About retesting
- How long should I make changes before repeating the fasting sugar and insulin behind this score?
- What change in my HOMA-IR would you regard as a real improvement rather than day-to-day variation?
Frequently asked questions
- What is HOMA-IR?
- This score combines your fasting sugar and fasting insulin into a single figure. When cells respond poorly, the pancreas pumps out extra insulin to hold sugar down, and that mismatch pushes the score up. This score estimates insulin resistance from two blood values you may already have, with no extra procedure.
- What is a normal insulin resistance score range?
- A typical adult range is around <2.0 often used as a reference cutoff; values vary by population and study methodology. No India-specific national reference interval is published for this parameter; your lab's printed range is the most reliable comparison. Ranges vary by lab, method and equipment — the range printed on your own report is the one that applies to your result.
- What does a high HOMA-IR result mean?
- A higher score suggests your cells may be responding to insulin less well. Your doctor reads it with your weight and other results. It is worth discussing with your doctor.
- What does a low HOMA-IR result mean?
- A lower score suggests your cells are responding to insulin well. This is generally the more reassuring direction.
- What can affect your HOMA-IR result?
- Several everyday factors can influence it, including whether you had fasted, your weight, where you carry fat, some medicines, a sudden illness.
