HOMA-IR is an index of insulin resistance derived from a single fasting sample. In its original linear approximation it is the product of fasting glucose and fasting insulin divided by a constant, and it correlates moderately with clamp-derived measures of insulin sensitivity across populations.[1]
Its appeal is that it requires one blood draw rather than a several-hour clamp. Its weakness is that it is a model-derived approximation from two values, inherits the poor standardisation of insulin assays, and describes hepatic rather than peripheral insulin resistance most directly.[2]
