A newer, more specific blood test for rheumatoid arthritis is the citrulline antibody test.

RA Diagnostic Test: Citrulline Antibody Test

Abnormal blood antibodies can be found in patients with rheumatoid arthritis. A blood antibody called “rheumatoid factor” can be found in 80% of patients. Citrulline antibody is present in most patients with rheumatoid arthritis. It is useful in the diagnosis of rheumatoid arthritis when evaluating patients with unexplained joint inflammation. A test for citrulline antibodies is most helpful in detecting the cause of previously undiagnosed inflammatory arthritis when the traditional blood test for rheumatoid arthritis, rheumatoid factor, is not present. Citrulline antibodies are also indicators of potentially more aggressive disease. Citrulline antibodies have been felt to represent the earlier stages of rheumatoid arthritis in this setting. Another antibody called “the antinuclear antibody” (ANA) is also frequently found in patients with rheumatoid arthritis.

This illustration shows the differences between a normal, healthy joint, a joint affected by osteoarthritis, and one affected by rheumatoid arthritis.

What Is the Difference Between Normal, Healthy Joints and Arthritic Joints?

A joint is where two bones meet to allow movement of body parts. Arthritis means joint inflammation. The joint inflammation of rheumatoid arthritis causes swelling, pain, stiffness, and redness in the joints. The inflammation of rheumatoid disease can also occur in tissues around the joints, such as the tendons, ligaments, and muscles. In some patients with rheumatoid arthritis, chronic inflammation leads to the destruction of the cartilage, bone, and ligaments, causing deformity of the joints. Damage to the joints can occur early in the disease and progress as the individual ages.
