Rheumatoid factor 600IU/ml high?

Rheumatoid factor 600 IU/ml is very high. The normal range of rheumatoid factor is usually low, generally 0 to 20 IU/ml. When the detection value reaches 600 IU/ml, it is obviously outside the normal range, indicating that severe rheumatoid arthritis or other autoimmune diseases may exist. First, high rheumatoid factor levels are highly suggestive of the possibility of rheumatoid arthritis. Rheumatoid arthritis is a common autoimmune disease that mainly affects joints, causing joint swelling, pain, stiffness and deformity. In patients with rheumatoid arthritis, rheumatoid factor is often significantly increased, but not all patients with elevated rheumatoid factor are rheumatoid arthritis, but also need to combine clinical symptoms and other tests to comprehensively judge. Secondly, in addition to rheumatoid arthritis, other autoimmune diseases such as Sjogren's syndrome, systemic lupus erythematosus, etc. may also appear elevated rheumatoid factor. These diseases can also cause varying degrees of damage to the body and require further diagnosis and targeted treatment. In addition, some non-autoimmune diseases, such as chronic infections, Rheumatoid factor (e.g. hepatitis, tuberculosis, etc.) may also cause mild elevation, but generally does not reach 600 IU/ml. For patients with rheumatoid factor 600 IU/ml, further detailed examination, including autoantibody testing, joint imaging, etc., is required to determine the cause and severity of the disease. At the same time, you should seek medical attention promptly and receive standardized treatment under the guidance of a doctor to control the progression of the disease, reduce symptoms, and improve your quality of life.
