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:

• \( Fasting\ Insulin \) — Insulin level in μU/mL
• \( Fasting\ Glucose \) — Glucose level in mg/dL

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/mL and fasting glucose in mg/dL. Both values must be valid (greater than 0).

5. Frequently Asked Questions (FAQ)

Q1: What is a normal HOMA-IR value?
A: Typically, values below 2.5 are considered normal, though this may vary by population and laboratory.

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

Q3: Are there limitations to HOMA-IR?
A: HOMA-IR may be less accurate in certain conditions like type 1 diabetes, pregnancy, or severe liver disease.

Q4: Can HOMA-IR be used for diagnosis?
A: While useful for screening and research, it should not be used alone for clinical diagnosis without additional tests.

Q5: How often should HOMA-IR be measured?
A: Frequency depends on individual risk factors and should be determined by a healthcare provider.
