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. This is the Australian version that uses mmol/L units for glucose measurement.

2. How Does the Calculator Work?

The calculator uses the HOMA-IR equation:

\[ HOMA-IR = \frac{(Fasting\ Insulin \times Fasting\ Glucose)}{22.5} \]

Where:

\( Fasting\ Insulin \) — Measured in μU/L (micro international units per liter)
\( Fasting\ Glucose \) — Measured in mmol/L (millimoles per liter)
22.5 — Normalization constant

Explanation: The equation provides a simple method to assess insulin resistance by evaluating 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 a key factor in metabolic syndrome, type 2 diabetes, and cardiovascular disease risk assessment.

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). Use morning fasting blood samples for accurate results.

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 2.5-3.0 may indicate insulin resistance. However, reference ranges may vary.

Q2: Why use mmol/L units for glucose?
A: This calculator uses mmol/L units as they are the standard measurement for glucose in Australia and many other countries outside the United States.

Q3: When should I get my insulin and glucose tested?
A: Morning fasting samples are required for accurate HOMA-IR calculation. Avoid testing after meals or vigorous exercise.

Q4: Are there limitations to HOMA-IR?
A: While useful for population studies and clinical screening, HOMA-IR may not be as accurate as more complex tests like hyperinsulinemic-euglycemic clamp in individual cases.

Q5: Can HOMA-IR be used for diagnosis?
A: HOMA-IR is a screening tool and should be used in conjunction with other clinical assessments for diagnosing insulin resistance or related conditions.
