HOMA-IR test: the insulin resistance index from two morning numbers
Included in the ₹1,799 home panel: collected at home where your pincode is served, and read by a doctor.
Start my free checkHOMA-IR is not a separate blood draw. It is a score calculated from fasting glucose and fasting insulin taken in the same sample, and it is the most widely used way to put a number on insulin resistance outside a research clinic.
What it is
What the HOMA-IR test measures
The calculation is simple: fasting insulin (in µIU/mL) multiplied by fasting glucose (in mg/dL), divided by 405. With glucose in mmol/L the divisor is 22.5. The model behind it was published by Matthews and colleagues in 1985 and describes how glucose and insulin balance each other overnight.
A higher score means more insulin is needed to hold glucose where it is — in other words, the body's tissues are responding less well to insulin. Two people with identical fasting sugar can have very different scores.
Why it matters
Why it matters for weight and metabolism
Insulin resistance is closely tied to fat stored around the organs, and South Asians tend to develop it at a lower body weight than Europeans. A HOMA-IR score gives that invisible pattern a number a doctor can plan around and re-measure.
It is also a measure that responds. Insulin sensitivity improves with strength training, better sleep and meals that raise glucose more gently, often before the scale moves much. A falling score is one of the earliest signs a plan is working at the level that matters.
Reading the result
How a result is usually read
Standard reference points, not a reading of anybody's own report. The interval your laboratory prints is the one that applies, and a doctor reads the number beside the rest of the panel and your history.
- Fasting glucose below 100 mg/dL
- The usual range. 100 to 125 mg/dL is impaired fasting glucose; 126 mg/dL or higher on repeat testing is the diabetes range.
- HOMA-IR has no single diagnostic threshold
- Cut-offs depend on the insulin assay and the population. In studies of Indian adults, values above roughly 2 to 2.5 have commonly been used to flag insulin resistance.
- A trend beats a single score
- Two scores from the same laboratory, months apart, say more than one score read against a published number.

At home
How it is collected at home
A phlebotomist from a partnered NABL-accredited laboratory draws one blood sample at your address, in a morning slot, and the laboratory reports the results to the doctor who reads your panel. Home collection depends on your pincode, which is checked before you pay.
HOMA-IR needs a fasting sample of 8 to 12 hours, plain water only, because both of its numbers are fasting values.
Glucose and insulin must come from the same draw; a score assembled from two different mornings is not valid.
The HOMA-IR test is part of the core of every Metaboliq panel, whatever else a doctor adds.
The limit
Its limits, stated plainly
HOMA-IR estimates insulin resistance; it does not measure it directly the way a clamp study in a research unit does. It varies from day to day, is less reliable once glucose is already high, and cannot say where in the body the resistance sits — liver or muscle. A doctor reads it beside HbA1c, triglycerides and the liver enzymes.

The tests a doctor reads with this one
A body is read as a whole. These are the results this one is most often read against.
- Fasting insulin test
What a fasting insulin test shows that a sugar test cannot: the early signal of insulin resistance, how results are read, and how to prepare for the draw.
- Fasting blood sugar test
Normal fasting, after-meal and average blood sugar levels in one chart: the commonly used cut-offs, what moves the number, and how to prepare for the test.
- Liver function test
What a liver function test measures — ALT, AST, GGT, ALP, bilirubin and albumin — what raised enzymes can mean for fatty liver, and what affects the result.

Questions
Questions people ask about the HOMA-IR test
Is HOMA-IR a separate blood test I have to book?
No. It is calculated from two results in one fasting sample — glucose and insulin. If both are measured, the score can be worked out; many laboratories print it on the report.
What is a normal HOMA-IR?
There is no universal normal. Healthy lean adults usually score low, and studies in India have often treated values above about 2 to 2.5 as a flag. Because insulin assays differ, a doctor reads your score against the laboratory's method and your other results.
Can a HOMA-IR score come down?
Yes. Insulin sensitivity responds to regular strength training, enough sleep, less refined carbohydrate and a smaller waist. Re-measuring after a few months, in the same laboratory, is how a doctor sees whether it has.
