QUICKI Calculator

Enter your patient's fasting insulin level (µU/ml) and fasting glucose level (mg/dL) to calculate their QUICKI score — the Quantitative Insulin Sensitivity Check Index. The result tells you how sensitive the body's cells are to insulin, with higher values indicating better insulin sensitivity.

Frequently Asked Questions

What is the QUICKI formula?

QUICKI is calculated as: 1 / [log(Fasting Insulin in µU/ml) + log(Fasting Glucose in mg/dL)]. It was developed by Katz et al. in 2000 as a simple, validated index of insulin sensitivity derived from fasting blood values.

What is insulin sensitivity?

Insulin sensitivity is a measure of how effectively the body's cells respond to insulin. Higher insulin sensitivity means insulin is more efficient at lowering blood sugar levels. It can be influenced by factors such as diet, physical activity, and body weight.

What is the meaning of insulin resistance?

Insulin resistance occurs when the body's cells do not respond adequately to insulin, leading to elevated blood glucose levels. Over time, this can progress to prediabetes and type 2 diabetes. It is often associated with obesity, sedentary lifestyle, and poor dietary habits.

What is the Quick Index of Insulin Sensitivity (QUICKI)?

QUICKI stands for Quantitative Insulin Sensitivity Check Index. It is a mathematical index derived from fasting insulin and fasting glucose that provides a reliable, non-invasive estimate of insulin sensitivity, useful in both clinical and research settings.

How do I interpret the QUICKI score?

In healthy individuals, QUICKI typically ranges from 0.45 to 0.30. A score above 0.45 suggests high insulin sensitivity, a score between 0.30 and 0.45 is considered normal, and a score below 0.30 indicates insulin resistance. Scores below 0.25 are associated with type 2 diabetes.

How do I use the QUICKI calculator?

Enter the patient's fasting insulin level in µU/ml and fasting glucose level in mg/dL — both obtained from a fasting blood sample. The calculator will instantly compute the QUICKI score and provide an interpretation of the result.

What are the benefits of using the QUICKI calculator?

The QUICKI calculator provides a quick, validated assessment of insulin sensitivity without requiring an insulin tolerance test or glucose clamp. It is particularly useful for screening and monitoring patients with diabetes, prediabetes, or metabolic syndrome.

How does QUICKI compare to HOMA-IR?

Both QUICKI and HOMA-IR are derived from fasting insulin and glucose values, but they use different mathematical transformations. QUICKI uses a log-based formula and produces values where higher scores mean better sensitivity, while HOMA-IR uses a product-based formula where higher values indicate more resistance. Both are well-validated in clinical research.
