1. What is HOMA-IR?

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 sensitivity from fasting blood glucose and insulin levels.

2. How Does the Calculator Work?

The calculator uses the HOMA-IR formula:

Where:

• Fasting Insulin — Measured in micro international units per milliliter (μU/mL)
• Fasting Glucose — Measured in milligrams per deciliter (mg/dL)

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

3. Importance of HOMA-IR Calculation

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

4. Using the Calculator

Tips: Enter fasting insulin in μU/mL and fasting glucose in mg/dL. Both values must be valid and greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal HOMA-IR value?
A: Typically, values below 1.0 indicate normal insulin sensitivity, while values above 2.0 suggest significant insulin resistance.

Q2: When should I test for HOMA-IR?
A: Testing should be done after an overnight fast (8-12 hours) for accurate results.

Q3: Are there limitations to HOMA-IR?
A: While useful for population studies, HOMA-IR may be less accurate in individuals with extreme insulin resistance or beta-cell dysfunction.

Q4: Can HOMA-IR diagnose diabetes?
A: HOMA-IR assesses insulin resistance but should not be used alone to diagnose diabetes. It's best used in conjunction with other tests.

Q5: How often should HOMA-IR be measured?
A: Frequency depends on individual risk factors and clinical context. Consult with a healthcare provider for personalized recommendations.
