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.

FAQs
Antibodies are proteins in your blood that your body’s immune system makes when it meets something that is not supposed to be in your body, such as a virus or bacteria. This helps our body to fight off disease. Autoantibodies are also proteins in your blood, but they are made in response to our own body’s tissue. This causes our body to think of itself as a threat and tries to fight it, causing damage and keeping our body from working the right way.
