التهاب المفاصل الروماتويدي
Rheumatoid arthritis is an autoimmune disorder. Detection of specific autoantibodies (antibodies directed against the body’s own tissue) such as rheumatoid factors and ACPAs may provide indication of the disease. In many cases, autoimmune diagnostics are crucial for diagnosing RA correctly and already in the disease’s early stages, when typical symptoms often are lacking but when medical therapy is most effective.
