Patient: He has been seen regularly since the onset of the disease in 2003 and has recovered well and is now largely asymptomatic. However, the rheumatoid factor has been very high and is now 529. In patients with rheumatoid arthritis, the level of rheumatoid factor is not proportional to the disease. It is one of the hallmark antibodies of the disease and does not usually change with the disease. Doctors also do not rely on it to determine the condition. So, there is no need to be nervous about it. Patient: Thank you, as you said, all my indicators are normal now except for high rheumatoid factor. I was almost desperate when I found out about this disease seven years ago, but after regular treatment, not only did I control the disease, but people who don’t know I have this disease can hardly see the abnormality. It’s the high rheumatoid factor that has always been a problem for me, and I’m relieved to hear you say it.
