What Is Seronegative Rheumatoid Arthritis?
If you’ve been told that you have seronegative rheumatoid arthritis, you’re probably wondering exactly what that is. It’s not unusual for your doctor to not fully explain it to you. All that you’ll usually be told is that you did not test positive for the rheumatoid factor. The rheumatoid factor is an immunoglobulin antibody that is found in the blood of around 80% of people with rheumatoid arthritis and is a common diagnostic tool for the disease. However, a certain number of people with the symptoms of the disease no not have this antibody. If that describes you, what does it mean for your prognosis?
