QUICKI Calculator
QUICKI (Quantitative Insulin Sensitivity Check Index) is a derived index used to evaluate insulin sensitivity. It is calculated using fasting blood glucose and fasting insulin levels.
Unlike HOMA-IR, where higher numbers indicate resistance, the QUICKI index correlates positively with insulin sensitivity: lower numbers indicate insulin resistance, while higher numbers indicate better insulin sensitivity.
Fasting Values
InputsResults
Normal: > 0.38
Insulin Resistant: < 0.34
Clinical Context
Formula:
QUICKI = 1 / [log10(Insulin in μIU/mL) + log10(Glucose in mg/dL)]
Interpretation:
• < 0.339: Insulin Resistant.
• 0.34 – 0.38: Borderline / Lower Sensitivity.
• > 0.382: Normal Insulin Sensitivity.
Advantage over HOMA: QUICKI relies on a logarithmic transformation, which some studies suggest provides a better linear correlation with the gold-standard euglycemic clamp, particularly in non-obese individuals.

How to Use This Calculator
Follow these steps to calculate the QUICKI Index.
Input Glucose
Enter the fasting glucose level. You can use mg/dL or mmol/L; the other field will update automatically.
Input Insulin
Enter the fasting insulin level. You can use μIU/mL or pmol/L.

The QUICKI score will appear instantly. Remember: Higher scores are better (more sensitive), unlike HOMA-IR.
Frequently Asked Questions
They are mathematically related (inversely). HOMA-IR is easier to visualize as “resistance” (high number = bad), while QUICKI is visualized as “sensitivity” (low number = bad).
Yes. Both glucose and insulin must be fasting levels (typically 8-12 hours) for the calculation to be valid.
