Rheumatoid Arthritis Factor
$129.99
This test detects and measures rheumatoid factor (RF) in the blood. RF is an autoantibody, an IgM (immunoglobulin M) protein that is produced by the body’s immune system. Autoantibodies attack a person’s own tissues, mistakenly identifying the tissue as “foreign.” While the biologic role of RF is not well understood, its presence is useful as an indicator of inflammatory and autoimmune activity.
Rheumatoid Factor IgA, IgG, IgM
Rheumatoid Arthritis (RA) is an autoimmune disease characterized by chronic, systemic inflammation, which predominantly affects the synovial membranes and articular structures in joints but may damage organs such as the heart and lungs.
Positive Rheumatoid Factor results are suggestive of RA, but the low specificity precludes a definitive diagnosis.Positive results are also common in patients with other rheumatic diseases and conditions that can mimic RA.
This is a non-fasting blood test that reports in 5-6 business days.
