🦴 2010 ACR/EULAR RA Classification Score
UseWhen to use: eligible synovitis (≥ 1 joint) not better explained by another disease.
Strata≥ 6 classifies definite RA; < 6 may evolve — reassess. Erosive RA typical pattern may classify separately.
LimitsWhen not to use: without definite synovitis, or when another disease … · Pitfall: mis-grading low vs high-positive RF/ACPA per local ULN defin… · Classification does not mandate a specific drug.

When to use
When to use: eligible synovitis (≥ 1 joint) not better explained by another disease.
How it works
Joints 0–5 + serology 0–3 + APR 0–1 + duration 0–1; ≥ 6/10 classifies definite RA.
Key points
- Eligibility gate first.

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.
| Definite clinical synovitis in ≥ 1 joint, not better explained elsewhere | No |
|---|---|
| Joint involvement | 1–3 small joints (± large) (2) |
| Serology | Low-positive RF or low-positive ACPA (2) |
| Acute-phase reactants | Normal CRP and normal ESR (0) |
| Symptom duration | < 6 weeks (0) |
→ACR/EULAR RANot applicable
- Requirement：Needs definite synovitis in ≥ 1 joint not better explained by another disease.
| Definite clinical synovitis in ≥ 1 joint, not better explained elsewhere | Yes (required) |
|---|---|
| Joint involvement | > 10 joints (≥ 1 small) (5) |
| Serology | High-positive RF or high-positive ACPA (3) |
| Acute-phase reactants | Abnormal CRP or abnormal ESR (1) |
| Symptom duration | ≥ 6 weeks (1) |
→ACR/EULAR score10/10
- Classification：≥ 6 — classifies as definite RA

Frequently asked questions
- Does 2010 ACR/EULAR RA Classification Score 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 2010 ACR/EULAR RA Classification Score calculated in practice? Can you show a worked example?
- Inputs: Definite clinical synovitis in ≥ 1 joint, not better explained elsewhere No, Joint involvement 1–3 small joints (± large) (2), Serology Low-positive RF or low-positive ACPA (2), Acute-phase reactants Normal CRP and normal ESR (0), Symptom duration < 6 weeks (0) → Result: ACR/EULAR RA Not applicable（Requirement: Needs definite synovitis in ≥ 1 joint not better explained by another disease.） Inputs: Definite clinical synovitis in ≥ 1 joint, not better explained elsewhere Yes (required), Joint involvement > 10 joints (≥ 1 small) (5), Serology High-positive RF or high-positive ACPA (3), Acute-phase reactants Abnormal CRP or abnormal ESR (1), Symptom duration ≥ 6 weeks (1) → Result: ACR/EULAR score 10 /10（Classification: ≥ 6 — classifies as definite RA）
