Formula & Clinical Notes

Formula

QUICKI = 1 / (log₁₀ Glucose + log₁₀ Insulin)

Clinical Notes

QUICKI = 1 / (log₁₀ glucose mg/dL + log₁₀ insulin µU/mL). Higher values indicate greater insulin sensitivity; lower values (typically below 0.34) suggest insulin resistance. QUICKI is less sensitive to fasting insulin assay noise than HOMA-IR.
