1. What is the HOMA-IR Equation?

The HOMA-IR (Homeostatic Model Assessment for Insulin Resistance) equation estimates insulin resistance using fasting insulin and glucose levels. It provides a simple and effective method to assess insulin sensitivity in clinical practice and research.

2. How Does the Calculator Work?

The calculator uses the HOMA-IR equation:

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

Where:

\( Fasting\ Insulin \) — Fasting insulin level in μU/L
\( Fasting\ Glucose \) — Fasting glucose level in mmol/L
22.5 — Normalization constant

Explanation: The equation quantifies 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 metabolic syndrome, type 2 diabetes, cardiovascular disease, and other metabolic disorders.

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 samples for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: What are normal HOMA-IR values?
A: Normal HOMA-IR values are typically below 2.0, though this may vary by population. Values above 2.5 often indicate insulin resistance.

Q2: When should insulin and glucose be measured?
A: Morning fasting samples are essential for accurate HOMA-IR calculation. Avoid testing after meals or vigorous exercise.

Q3: 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, but it's practical for clinical use.

Q4: Can HOMA-IR be used for diagnosis?
A: While HOMA-IR is a useful screening tool, clinical diagnosis should be based on comprehensive assessment including other tests and clinical evaluation.

Q5: Does HOMA-IR vary by ethnicity?
A: Yes, cutoff values for insulin resistance may vary among different ethnic populations, so population-specific references should be considered.
