About the Test
Rheumatoid arthritis (RA) is a long-term autoimmune disease that causes your body to attack healthy cells instead of bacteria or viruses. This disease causes painful swelling in the parts of the body being attacked, typically your joints (e.g., wrists, knees, and hands) but also other tissues like your eyes, lungs, and heart. The damage caused to tissues can lead to long-term pain, poor balance, and misshaped joints. Symptoms typically begin between 30-50 years of age. Our Rheumatoid Arthritis Test looks for certain proteins and autoantibodies in your blood to help detect RA. This information, along with clinical history and physical examination, can be used to identify next steps.
