Low-normal insulin sensitivity
How to use it
- 1
Fasting samples (minimum 8h fast). Serum glucose in mmol/L, insulin in µIU/mL.
- 2
HOMA-IR = (glucose × insulin) / 22.5. Threshold for IR varies by lab and ethnicity: often > 2.5 or > 3.0.
- 3
Limitations. Single time-point; affected by acute illness, corticosteroids, recent food.
When to use it
- PCOS evaluation
- HOMA-IR > 2.5 in PCOS supports metformin use.
