Understanding Your RA Panel
The RA panel helps diagnose rheumatoid arthritis, an autoimmune condition that causes joint pain and swelling. It measures two antibodies linked to the disease.
What It Measures
In rheumatoid arthritis, the immune system attacks the joints. These blood tests look for antibodies often found in that process.
| Component | What It Means |
|---|---|
| RFRheumatoid Factor | An antibody found in many people with rheumatoid arthritis. It can also be positive in other conditions or in healthy people, so it is not specific by itself. |
| Anti-CCPCyclic Citrullinated Peptide Antibody | A more specific marker for rheumatoid arthritis. A positive anti-CCP strongly supports the diagnosis and can appear early. |
What’s Most Important to Know
Neither test alone diagnoses rheumatoid arthritis. The diagnosis is based on your symptoms, joint exam, and these labs together, sometimes with imaging.
A positive anti-CCP is more meaningful than RF alone. If the panel or your symptoms suggest rheumatoid arthritis, Dr. Mui may refer you to a rheumatologist for specialized care.
