QUICKI Calculator
Metabolic Relevance
QUICKI correlates strongly with the euglycemic clamp (r ≈ 0.78), the gold standard for measuring insulin sensitivity. Unlike HOMA-IR which measures resistance (lower is better), QUICKI measures sensitivity (higher is better) — making interpretation more intuitive.
Recommended testing frequency:
Every 3-6 months after lifestyle changes, annually when stable
Did you know?
QUICKI and HOMA-IR use the exact same lab values — fasting glucose and fasting insulin. The logarithmic transformation in QUICKI creates an inverse scale: QUICKI > 0.45 corresponds to HOMA-IR < 1.0.
On ketogenic diets, adaptive glucose sparing can elevate fasting glucose without true insulin resistance — always combine with TG/HDL ratio for context.
