HOMA-IR Calculator
Insulin Resistance Assessment Tool
Calculate HOMA-IR & QUICKI Index
Important:
Both values must be obtained after fasting for at least 8 hours (water only).
Normal range: 70-100 mg/dL
Normal range: 2-25 mU/L (varies by lab)
HOMA-IR Reference Ranges
QUICKI Index Ranges
Key Information
Requires 8+ hours fasting before blood draw
Simple alternative to invasive testing
Helps assess diabetes and prediabetes risk
Results may vary between populations
Understanding HOMA-IR and Insulin Resistance
What is HOMA-IR?
HOMA-IR (Homeostatic Model Assessment for Insulin Resistance) is a simple method to quantify insulin resistance using fasting glucose and insulin levels. It provides an estimate of insulin resistance without requiring complex testing procedures.
HOMA-IR Formula
HOMA-IR = (insulin * glucose) / 405
When glucose is in mg/dL
HOMA-IR = (insulin * glucose) / 22.5
When glucose is in mmol/L
What is QUICKI?
QUICKI (Quantitative Insulin Sensitivity Check Index) is another measure of insulin sensitivity that uses the same fasting values but with a logarithmic formula.
QUICKI = 1 / (log(insulin) + log(glucose))
Lower values indicate worse insulin sensitivity
What is Insulin Resistance?
Insulin resistance occurs when cells become less responsive to insulin, requiring higher levels to maintain normal blood glucose. This condition often precedes type 2 diabetes and is associated with metabolic syndrome.
Risk Factors
- •Obesity, especially abdominal fat
- •Sedentary lifestyle
- •Family history of diabetes
- •Age over 45 years
- •High blood pressure
- •High triglycerides or low HDL cholesterol
Improving Insulin Sensitivity
- ✓Regular aerobic and resistance exercise
- ✓Weight loss (even 5-10% helps significantly)
- ✓Low-glycemic diet with whole grains
- ✓Adequate sleep (7-9 hours per night)
- ✓Stress management techniques
