rheumatoid factor (rf)

Rheumatoid Factor (RF) is an immunoglobulin M protein, produced by the body’s immune system. This protein attacks the body’s tissues as it mistakenly identifies them as a foreign entity. The rheumatoid factor test determines the level of rheumatoid factor in your blood to diagnose rheumatoid arthritis. Higher RF concentrations are often linked to autoimmune disorders such as rheumatoid arthritis and Sjogren’s syndrome. Other conditions that may elevate RF concentration in the blood include hepatitis, viral or bacterial infections, and endocarditis. There is also a gradual rise in RF levels with age. Book a Rheumatoid Factor test from Thyrocare to avail of the service at your doorsteps at a low cost.
