What does anti-o rheumatoid factor mean?

Anti-O and rheumatoid factor are important indicators for the diagnosis of certain diseases.

Anti-O is called anti-streptolysin O, which is the antibody produced by the body against streptolysin O. When the human body is infected with group A hemolytic streptococci, it will stimulate the body to produce anti-O. Its level is often increased after streptococci infection, such as acute tonsillitis, scarlet fever, etc. In addition, abnormal elevations may occur in autoimmune diseases such as rheumatic fever.

Rheumatoid factor is an autoantibody that is present primarily in the serum and joint fluid of patients with rheumatoid arthritis. Rheumatoid factor may also be positive in other autoimmune diseases such as Sjogren's syndrome and systemic lupus erythematosus. At the same time, there may be low titer rheumatoid factor in some healthy elderly people. It

should be noted that the detection of anti-O or rheumatoid factors alone cannot diagnose a disease, but also needs to be combined with clinical symptoms, signs and other related examinations for comprehensive judgment. In clinical practice, doctors will conduct comprehensive analysis and evaluation according to specific conditions to accurately diagnose the disease and formulate a reasonable treatment plan.
