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 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
• Fasting Glucose — Measured in mmol/L
• 22.5 — Normalization constant

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

3. Importance of HOMA-IR Calculation

Details: HOMA-IR is important for assessing insulin resistance, which is associated with 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 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.

Q2: How often should HOMA-IR be measured?
A: It should be measured as part of metabolic health assessments, particularly in individuals at risk for insulin resistance.

Q3: Are there limitations to HOMA-IR?
A: Yes, it may not be accurate in certain conditions such as type 1 diabetes or when beta-cell function is severely impaired.

Q4: Can HOMA-IR be used for diagnosis?
A: It is a screening tool and should be used alongside other clinical assessments for diagnosis.

Q5: What factors affect HOMA-IR results?
A: Factors include recent food intake, physical activity, medications, and overall metabolic health.
