1. What is the HOMA2 Calculator?

The HOMA2 (Homeostatic Model Assessment 2) calculator is an updated computational model that estimates insulin resistance (HOMA2-IR) and beta-cell function (HOMA2-%B) from fasting insulin and glucose levels. It provides a more accurate assessment than the original HOMA1 model.

2. How Does the Calculator Work?

The HOMA2 model uses a complex computational algorithm based on:

Non-linear mathematical model that solves differential equations representing glucose-insulin homeostasis

Input Parameters:

Fasting Insulin (μU/mL or pmol/L)
Fasting Glucose (mg/dL or mmol/L)

Output Values:

HOMA2-IR - Insulin resistance index
HOMA2-%B - Beta-cell function percentage
HOMA2-%S - Insulin sensitivity percentage

3. Importance of HOMA2-IR Calculation

Details: HOMA2-IR is crucial for assessing insulin resistance in research and clinical settings, helping identify individuals at risk for type 2 diabetes and metabolic syndrome.

4. Using the Calculator

Tips: Enter fasting insulin and glucose values with appropriate units. For accurate results, measurements should be taken after an overnight fast of 8-12 hours.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between HOMA1 and HOMA2?
A: HOMA2 uses a more complex computational model that accounts for variations in hepatic and peripheral glucose resistance, providing more accurate results across different physiological states.

Q2: What are normal HOMA2-IR values?
A: Normal HOMA2-IR values are typically <1.8. Values between 1.8-2.9 indicate moderate insulin resistance, while values >2.9 suggest significant insulin resistance.

Q3: When should insulin and glucose be measured?
A: Morning fasting samples after an 8-12 hour overnight fast are ideal for accurate HOMA2 calculations.

Q4: Are there limitations to the HOMA2 model?
A: The model may be less accurate in patients with type 1 diabetes, liver disease, or those using medications that significantly affect glucose metabolism.

Q5: Can HOMA2 be used for clinical diagnosis?
A: While HOMA2 is widely used in research, clinical diagnosis of insulin resistance should be based on comprehensive assessment including oral glucose tolerance tests when necessary.
