QUICKI (Quantitative Insulin Sensitivity Check Index) is a fasting surrogate marker of insulin sensitivity calculated from fasting glucose and fasting insulin. Compared with HOMA-IR, QUICKI inversely scales with insulin resistance, so lower values generally suggest greater insulin resistance.
Formula: QUICKI = 1 / (log10(Fasting Insulin) + log10(Fasting Glucose))
Lower QUICKI values generally reflect lower insulin sensitivity and may indicate higher insulin resistance.
Use QUICKI in metabolic risk assessment when fasting insulin and fasting glucose are available, especially for trend tracking over time.
Reference cutoffs vary across populations and assays. QUICKI is not a stand-alone diagnostic test and should be interpreted in clinical context.
For related assessments, see HOMA-IR, HbA1c Converter and TyG Index.

Estimate insulin resistance using fasting glucose and fasting insulin with the HOMA-IR equation.
EndocrinologyConvert HbA1c to estimated average glucose (eAG): 6%=126 mg/dL, 7%=154, 8%=183, 9%=212. ADA 2026 target <7% for most adults with diabetes. Shows both mg/dL and mmol/L.
CardiologyCalculate the Triglyceride-Glucose (TyG) Index from fasting triglycerides and fasting glucose to assess insulin resistance patterns.
