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 simple method to assess insulin sensitivity and identify potential 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, with higher values indicating greater insulin resistance.

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 disease risk assessment.

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). For accurate results, measurements should be taken after an overnight fast.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal HOMA-IR value?
A: Typically, values below 2.0 are considered normal, while values above 2.5 may indicate insulin resistance. However, reference ranges may vary.

Q2: When should I get tested for HOMA-IR?
A: Testing is recommended for individuals with risk factors for insulin resistance, such as obesity, family history of diabetes, or polycystic ovary syndrome.

Q3: How should I prepare for the test?
A: A 8-12 hour overnight fast is required before blood collection for both insulin and glucose measurements.

Q4: Are there limitations to HOMA-IR?
A: HOMA-IR provides an estimate and may not be as accurate as more complex tests like hyperinsulinemic-euglycemic clamp, which is the gold standard.

Q5: Can HOMA-IR be used for diagnosis?
A: While HOMA-IR is a useful screening tool, clinical diagnosis should be based on comprehensive evaluation including medical history and additional tests.
