- Anti-nuclear antibody (ANA)
- Anti-cyclic citrullinated peptide (anti-CCP) antibodies.
- C-reactive protein (CRP)

What is a rheumatoid factor blood test?
A rheumatoid factor (RF) test detects rheumatoid factor in a patient’s blood. Rheumatoid factor is an autoantibody produced by the immune system. While normal antibodies attack pathogens like bacteria and viruses, autoantibodies such as RF mistakenly attack the body’s healthy cells and tissues.

- Weight loss.
- Stiffness.
- Joint tenderness.
- Joint pain.
- Joint swelling.
- Joint redness.
What does CCP positive mean?

What causes a positive RF test for RA?
In some cases, certain viruses can trigger symptoms similar to those of RA and lead to a positive RF test result. Examples of viruses that can cause this include parvovirus B19 and hepatitis C. A person may need to have additional tests, such as a hepatitis C antibody test, to exclude these viral infections.
Can a child test positive for rheumatoid arthritis?
