Also written Insulin resistance index
A calculated index combining fasting glucose and fasting insulin into a single estimate of insulin resistance.
It compresses two related measurements into one interpretable number and is widely used in metabolic research.
Measured in index. Each row is one claim about where your result should fall.

Where the sources disagree
HOMA-IR is the clearest illustration of why biomarker counts are misleading. It is arithmetic performed on two other results, yet it commonly appears as a separate line item on a panel that advertises '100+ biomarkers'. You did not receive a third measurement. You received a division problem. This distinction, measured versus derived, is exactly what is being litigated in the industry right now, and it is why our Panel Audit separates the two counts.
Each claim gets its strongest possible case before it gets its criticism. Several of these are substantially correct.
Under 1.0
Promoted by longevity platforms and metabolic optimization programs
Combining fasting glucose and insulin captures more information than either alone, and lower values do track with better insulin sensitivity.
HOMA-IR is calculated, not measured. It inherits every problem of the insulin assay it depends on, and it was developed for comparing populations in research, not for grading individuals against a target.
