ACR/EULAR 2010 RA Classification Criteria

Scores the 2010 ACR/EULAR rheumatoid arthritis classification criteria across four domains: joint involvement (0–5), serology (0–3), acute-phase reactants (0–1), and symptom duration (0–1). Score ≥6 out of 10 classifies as definite RA.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Scores the 2010 ACR/EULAR rheumatoid arthritis classification criteria across four domains: joint involvement (0–5), serology (0–3), acute-phase reactants (0–1), and symptom duration (0–1). Score ≥6 out of 10 classifies as definite RA

Each component has a specific meaning:

  • Four domains: joint involvement — The four domains: joint involvement recorded for the scenario being assessed.
  • Serology — The serology recorded for the scenario being assessed.
  • Acute-phase reactants — The acute-phase reactants recorded for the scenario being assessed.
  • Symptom duration — The symptom duration recorded for the scenario being assessed.

Note: Interpret the acr/eular ra 2010 result against the thresholds and context described above.

How to Use

Enter the four domains: joint involvement, serology, acute-phase reactants, symptom duration for the scenario you are assessing. Scores the 2010 ACR/EULAR rheumatoid arthritis classification criteria across four domains: joint involvement (0–5), serology (0–3), acute-phase reactants (0–1), and symptom duration (0–1). Score ≥6 out of 10 classifies as definite RA. Use the acr/eular ra 2010 result to inform your calculation.
