Normal range: 2-25 µU/ml (fasting, 8-12 hours)
Normal range: 70-100 mg/dL (fasting)
QUICKI Calculation Results
Example Calculation
Sample Patient Data
Fasting insulin: 15 µU/ml
Fasting glucose: 103 mg/dL
QUICKI Calculation
Step 1: log₁₀(15) = 1.176
Step 2: log₁₀(103) = 2.013
Step 3: QUICKI = 1 / (1.176 + 2.013) = 1 / 3.189
Result: QUICKI = 0.313
Interpretation: Indicates insulin resistance (below 0.339 threshold)
QUICKI Reference Ranges
Values below 0.339 indicate insulin resistance

Understanding QUICKI and Insulin Sensitivity
What is QUICKI?
QUICKI (Quantitative Insulin Sensitivity Check Index) is a mathematical formula developed by Katz et al. in 2000 to assess insulin sensitivity using fasting insulin and glucose levels. It provides a simple alternative to complex glucose clamp procedures.
Insulin Sensitivity vs. Resistance
- •High sensitivity: Cells respond well to insulin, maintaining normal blood sugar
- •Low sensitivity: Cells resist insulin action, leading to higher blood sugar
- •Insulin resistance: Body produces more insulin to compensate for poor cellular response
Risk Factors for Insulin Resistance
Symptoms of Insulin Resistance
Improving Insulin Sensitivity
Exercise Regularly
Both aerobic exercise and resistance training improve insulin sensitivity. Aim for 150 minutes of moderate activity per week.
Maintain Healthy Weight
Even modest weight loss (5-10%) can significantly improve insulin sensitivity.
Balanced Diet
Focus on whole foods, fiber-rich vegetables, lean proteins, and healthy fats. Limit processed foods and added sugars.
