Quantitative insulin sensitivity check index

The quantitative insulin sensitivity check index ("QUICKI") is derived using the inverse of the sum of the logarithms of the fasting insulin and fasting glucose:

:"1 / (log(fasting insulin µU/mL) + log(fasting glucose mg/dL))"

This index correlates well with glucose clamp studies (r = 0.78), and is useful for measuring insulin sensitivity (IS), which is the inverse of insulin resistance (IR). It has the advantage of that it can be obtained from a fasting blood sample, and is the preferred method for certain types of clinical research.
