To confirm a diagnosis of rheumatoid arthritis (RA), several tests are typically used in combination, as no single test can definitively diagnose the condition. Here are the key tests:

1. **Blood Tests:**
- **Rheumatoid Factor (RF):** Measures an antibody that is present in many, but not all, people with RA.
- **Anti-Cyclic Citrullinated Peptide (anti-CCP):** Highly specific for RA and can confirm the diagnosis if positive.
- **Erythrocyte Sedimentation Rate (ESR) and C-Reactive Protein (CRP):** These tests measure inflammation levels, which are often elevated in RA.

2. **Imaging Tests:**
- **X-rays:** Can detect joint damage and erosion caused by RA.
- **Ultrasound and MRI:** These imaging tests can identify early signs of joint inflammation and damage not visible on X-rays.

3. **Physical Examination:**
- A thorough physical exam by a rheumatologist, focusing on joints for signs of swelling, tenderness, and deformity.

4. **Medical History:**
- Detailed discussion of symptoms, duration, and family history of RA or other autoimmune diseases.

These tests, combined with a clinical evaluation, help in forming a comprehensive view necessary for an accurate RA diagnosis.
