1. What is the HOMA-IR Calculator?

The HOMA-IR (Homeostatic Model Assessment for Insulin Resistance) calculator estimates insulin resistance using fasting insulin and glucose levels. It provides a quantitative measure of insulin resistance, which is a key factor in metabolic disorders.

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 insulin and glucose levels.

3. Importance of HOMA-IR Calculation

Details: HOMA-IR is crucial for identifying insulin resistance, which is associated with type 2 diabetes, metabolic syndrome, 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: Normal HOMA-IR values are typically below 2.0, though this may vary by population and laboratory standards.

Q2: Why use HOMA-IR?
A: HOMA-IR is a simple, non-invasive method to estimate insulin resistance and is widely used in clinical and research settings.

Q3: When should insulin and glucose be measured?
A: Both should be measured after an overnight fast (8-12 hours) for accurate results.

Q4: Are there limitations to HOMA-IR?
A: HOMA-IR may be less accurate in individuals with extreme insulin levels or those with pancreatic dysfunction.

Q5: Can HOMA-IR be used for diagnosis?
A: While HOMA-IR is a useful screening tool, it should be used in conjunction with other clinical assessments for diagnosis.
