There is no specific test to confirm rheumatoid arthritis.
Hence, the doctor has to rely on medical history and physical examination of the joint to diagnose rheumatoid arthritis.
Laboratory tests that help in the diagnosis are:
- Rheumatoid factor (RF) test
- Anti-CCP antibody test
Other tests that may be done include:
- Complete blood count (CBC)
- C-reactive protein
- Erythrocyte sedimentation rate (ESR)
- X-ray, ultrasound or MRI of the affected joint
- Synovial fluid analysis
