1. What is the HOMA-IR Index?

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.

2. How Does the Calculator Work?

The calculator uses the HOMA-IR equation:

\[ HOMA-IR = \frac{\text{Fasting Insulin} \times \text{Fasting Glucose}}{22.5} \]

Where:

Fasting Insulin — Measured in μU/L (microinternational units per liter)
Fasting Glucose — Measured in mmol/L (millimoles per liter)
22.5 — Normalization constant

Explanation: The equation estimates insulin resistance by assessing the relationship between fasting glucose and insulin levels.

3. Importance of HOMA-IR Calculation

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.

4. Using the Calculator

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.

5. Frequently Asked Questions (FAQ)

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.
