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:

Where:

• \( Fasting\ Insulin \) — Fasting insulin level in μU/L
• \( Fasting\ Glucose \) — Fasting glucose level in mmol/L

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 crucial for identifying insulin resistance, which is associated with metabolic syndrome, type 2 diabetes, 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).

5. Frequently Asked Questions (FAQ)

Q1: What are normal HOMA-IR values?
A: Normal HOMA-IR values are typically below 2.5. Values above 2.5 may indicate insulin resistance.

Q2: When should insulin and glucose be measured?
A: Both should be measured after an overnight fast of 8-12 hours for accurate results.

Q3: Are there limitations to this calculation?
A: HOMA-IR may be less accurate in certain populations, such as those with type 1 diabetes or severe insulin resistance.

Q4: Can HOMA-IR be used for diagnosis?
A: While HOMA-IR is a useful screening tool, it should not be used alone for diagnosis. Clinical evaluation and other tests are necessary.

Q5: What units are required for the calculation?
A: Insulin must be in μU/L and glucose in mmol/L for the standard HOMA-IR formula.
