The relationship between blood sedimentation and rheumatoid arthritis needs to be determined on a case-by-case basis. If a patient with rheumatoid arthritis has significant joint swelling and pain, and the blood sedimentation and C-reactive protein are significantly elevated, it indicates that the patient’s rheumatoid arthritis is in the active stage, and the inflammatory reaction of the whole body is obvious, so active anti-rheumatic treatment is needed to control the activity of the disease, and the blood sedimentation can be reduced. However, if a patient with rheumatoid arthritis does not have obvious joint pain, swollen joints and pain, and the C-reactive protein is not high, the elevated blood sedimentation may not be related to rheumatoid arthritis itself. It is important to find out whether the patient has anemia or other diseases such as tumors in combination. Blood sedimentation is not a specific clinical test for rheumatoid arthritis.
