About this test
The RA Factor test measures rheumatoid factor levels in the blood to help diagnose rheumatoid arthritis and other autoimmune conditions.

The RA Factor (Rheumatoid Factor) test is a blood test used to detect the presence of rheumatoid factor, an antibody that can attack healthy tissues in the body. It is commonly associated with autoimmune disorders, particularly rheumatoid arthritis.

Elevated rheumatoid factor levels may indicate rheumatoid arthritis, but they can also be seen in other autoimmune diseases, chronic infections, and inflammatory conditions. Therefore, this test is usually interpreted along with clinical findings and other diagnostic tests.

Test Recommended For

  • Individuals with joint pain or swelling
  • Patients with suspected rheumatoid arthritis
  • People with symptoms like stiffness or fatigue
  • Individuals with autoimmune disease symptoms
  • Patients advised for arthritis evaluation
