However a score of 6 or greater unequivocally classifies a person with a diagnosis of rheumatoid arthritis.These new classification criteria overruled the "old" ACR criteria of 1987 and are adapted for early RA diagnosis. The "new" classification criteria, jointly published by the American College of Rheumatology (ACR) and the European League Against Rheumatism (EULAR) establish a point value between 0 and 10. Four areas are covered in the diagnosis:
joint involvement, designating the metacarpophalangeal joints, proximal interphalangeal joints, the interphalangeal joint of the thumb, second through fifth metatarsophalangeal joint and wrist as small joints, and shoulders, elbows, hip joints, knees, and ankles as large joints:
Involvement of 1 large joint gives 0 points
Involvement of 2–10 large joints gives 1 point
Involvement of 1–3 small joints (with or without involvement of large joints) gives 2 points
Involvement of 4–10 small joints (with or without involvement of large joints) gives 3 points
Involvement of more than 10 joints (with involvement of at least 1 small joint) gives 5 points
serological parameters – including the rheumatoid factor as well as ACPA – "ACPA" stands for "anti-citrullinated protein antibody":
Negative RF and negative ACPA gives 0 points
Low-positive RF or low-positive ACPA gives 2 points
High-positive RF or high-positive ACPA gives 3 points
acute phase reactants: 1 point for elevated erythrocyte sedimentation rate, ESR, or elevated CRP value (c-reactive protein)
duration of arthritis: 1 point for symptoms lasting six weeks or longerThe new criteria accommodate to the growing understanding of RA and the improvements in diagnosing RA and disease treatment.
