Homeostasis model assessment (HOMA) is a diagnostical procedure that is based on the homeostasis model of carbohydrate metabolism.
1 Physiological foundation
The HOMA approach is grounded in the homeostasis model of Turner et al., a mathematical model of feedback coupled interaction of insulin and glucose in carbohydrate homeostasis.
2 Calculation
In HOMA, simultaneously determined glucose and insulin levels in fasting state are entered in equations that calculate beta cell function and insulin sensitivity.
- HOMA Beta = 20 * fasting insulin (mU/l) / (fasting glucose (mmol/l) - 3,5)
- HOMA IR = fasting insulin (mU/l) * fasting glucose (mmol/l) / 22,5
