🧴 EASI (Eczema Area and Severity Index)
UseWhen to use: AD trials, systemic therapy counseling, and longitudinal severity tracking.
StrataHigher EASI marks more severe disease; common trial bands <7 / 7–21 / >21.
LimitsWhen not to use: replacing full dermatology exam. · Pitfall: inconsistent sign grading across visits. · Not a sole systemic Rx order.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.

FAQ
Frequently asked questions
- Does EASI (Eczema Area and Severity Index) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is EASI (Eczema Area and Severity Index) calculated in practice? Can you show a worked example?
- Inputs: Head/neck severity (E+I+Ex+L, 0–12) 4, Head/neck area (0–6) 3 — 30–49%, Trunk severity (0–12) 6, Trunk area (0–6) 3, Upper extremities severity (0–12) 5, Upper extremities area (0–6) 3, Lower extremities severity (0–12) 7, Lower extremities area (0–6) 3 → Result: EASI 18.0 /72（Head/neck: 1.20, Trunk: 5.40, Upper extremities: 3.00） Inputs: Head/neck severity (E+I+Ex+L, 0–12) 4, Head/neck area (0–6) 0 — none, Trunk severity (0–12) 6, Trunk area (0–6) 0, Upper extremities severity (0–12) 5, Upper extremities area (0–6) 0, Lower extremities severity (0–12) 7, Lower extremities area (0–6) 0 → Result: EASI 0.0 /72（Head/neck: 0.00, Trunk: 0.00, Upper extremities: 0.00）
