HOMA-IR Equation:

The HOMA-IR (Homeostatic Model Assessment for Insulin Resistance) is a method used to quantify insulin resistance and beta-cell function. It provides an assessment of insulin resistance from fasting blood glucose and insulin levels.
The calculator uses the HOMA-IR equation:
Where:
Explanation: The equation estimates insulin resistance by assessing the relationship between fasting glucose and insulin levels.
Details: HOMA-IR is a valuable tool for assessing insulin resistance, which is associated with various metabolic disorders including type 2 diabetes, metabolic syndrome, and cardiovascular diseases.
Tips: Enter fasting insulin in μU/L and fasting glucose in mmol/L. Both values must be valid (greater than 0). For accurate results, measurements should be taken after an overnight fast.
Q1: What is a normal HOMA-IR value?
A: Typically, values below 2.0 are considered normal, though this may vary depending on the population and laboratory standards.
Q2: How does HOMA-IR relate to diabetes risk?
A: Higher HOMA-IR values indicate greater insulin resistance, which is a significant risk factor for developing type 2 diabetes.
Q3: When should insulin and glucose be measured?
A: Both should be measured after an overnight fast (8-12 hours) for accurate HOMA-IR calculation.
Q4: Are there limitations to the HOMA-IR model?
A: While useful for population studies, HOMA-IR may be less accurate in individuals with extreme insulin resistance or beta-cell dysfunction.
Q5: Can HOMA-IR be used for clinical diagnosis?
A: HOMA-IR is primarily used for research and screening purposes. Clinical diagnosis should be based on comprehensive assessment including oral glucose tolerance tests when necessary.
