1. What is the HOMA-IR Index?

The HOMA-IR (Homeostatic Model Assessment for Insulin Resistance) index is a method used to quantify insulin resistance and beta-cell function. It provides an estimate of insulin resistance from fasting blood glucose and insulin levels.

2. How Does the Calculator Work?

The calculator uses the HOMA-IR equation:

Where:

• Fasting Insulin — Measured in μU/L (micro international units per liter)
• Fasting Glucose — Measured in mmol/L (millimoles per liter)

Explanation: The equation calculates insulin resistance by assessing the relationship between fasting insulin and glucose levels, with higher values indicating greater insulin resistance.

3. Importance of HOMA-IR Calculation

Details: HOMA-IR is a valuable tool for assessing insulin resistance, which is associated with metabolic syndrome, type 2 diabetes, cardiovascular disease, and other health conditions.

4. Using the Calculator

Tips: Enter fasting insulin in μU/L and fasting glucose in mmol/L. Both values must be greater than zero for accurate calculation.

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 by population and laboratory standards.

Q2: When should HOMA-IR testing be done?
A: Testing should be performed after an overnight fast of 8-12 hours for accurate results.

Q3: Are there limitations to the HOMA-IR index?
A: Yes, it may be less accurate in certain populations such as those with type 1 diabetes, liver disease, or taking certain medications.

Q4: How often should HOMA-IR be measured?
A: Frequency depends on individual risk factors and clinical context, typically as part of metabolic health assessment.

Q5: Can HOMA-IR be used for diagnosis?
A: While it's a useful screening tool, diagnosis of insulin resistance should be confirmed with additional clinical assessment and tests.
