What tests are recommended to confirm a diagnosis of rheumatoid arthritis?
A diagnosis of rheumatoid arthritis is made with a combination of clinical history and physical examination along with laboratory tests, and sometimes X-rays. Patients with RA usually have prolonged morning stiffness and afternoon fatigue. The usual joints affected are the fingers and toes. The most helpful laboratory tests are an anti-CCP antibody test along with a rheumatoid factor. Only 10% of patients are negative for both tests. Occasionally individuals with RA have neck (cervical spine) problems. More information about diagnosing rheumatoid arthritis and spine problems can be found here:
