QUICKI Calculator

Enter Fasting Data

Use fasting lab values only. QUICKI uses fasting glucose and fasting insulin after unit conversion to mg/dL and uU/mL.

Example Data Table

These sample values are for demonstration only and help show how the score responds to different fasting glucose and insulin combinations.

Case	Fasting Glucose (mg/dL)	Fasting Insulin (uU/mL)	QUICKI	Example Reading
Case A	78	4	0.401	Higher relative sensitivity benchmark
Case B	85	6	0.369	Intermediate benchmark zone
Case C	95	10	0.336	Intermediate benchmark zone
Case D	110	18	0.303	Lower relative sensitivity benchmark

Formula Used

QUICKI = 1 / ( log10(Fasting Insulin in uU/mL) + log10(Fasting Glucose in mg/dL) )

Glucose entered in mmol/L is converted to mg/dL by multiplying by 18.
Insulin entered in pmol/L is converted to uU/mL by dividing by 6.945.
The calculator applies base-10 logarithms to the converted fasting values.
Higher QUICKI values generally indicate greater insulin sensitivity in relative terms.

FAQs

1) What does QUICKI measure?

QUICKI is a fasting-data index used to estimate insulin sensitivity from glucose and insulin values after logarithmic transformation.

2) Do I need fasting samples?

Yes. QUICKI is designed for fasting glucose and fasting insulin values. Non-fasting results can distort the estimate and reduce usefulness.

3) Which units are supported?

The calculator supports glucose in mg/dL or mmol/L and insulin in uU/mL or pmol/L, then converts them into the required formula units.

4) Does age or BMI change the equation?

No. Age, sex, BMI, and waist circumference do not change the QUICKI formula here. They are included only to add context to the report.

5) Why is the graph useful?

The graph helps visualize how the QUICKI score would move if glucose changed while insulin remained fixed at the entered fasting level.

6) Can this calculator diagnose insulin resistance?

No. It is a screening and review tool. Diagnosis requires clinical history, examination, and interpretation of broader laboratory findings.

7) Why can a small input change alter the score?

QUICKI uses logarithms and a reciprocal, so even modest glucose or insulin shifts can create a visible movement in the final value.

8) What should I export?

Export the CSV for structured records and the PDF for sharing or printing a formatted result summary with chart and interpretation.
