HOMA-IR stands for Homeostatic Model Assessment of Insulin Resistance. The meaningful part of the acronym is “insulin resistance”. It marks for both the presence and extent of any insulin resistance that you might currently express. It is a terrific way to reveal the dynamic between your baseline (fasting) blood sugar and the responsive hormone insulin. See The Blood Code book for further insight about your result.

Healthy Range: 1.0 (0.5–1.4)
Less than 1.0 means you are insulin-sensitive which is optimal.
Above 1.9 indicates early insulin resistance.
Above 2.9 indicates significant insulin resistance.

The HOMA-IR calculation requires U.S. standard units. To convert from international S.I. units:
Insulin: pmol/L to uIU/mL, divide by (÷) 6
Glucose: mmol/L to mg/dL, multiply by (x) 18
