Rheumatology four items include blood sedimentation, rheumatoid factor, anti-streptococcal hemolysin “O” and C-reactive protein. Blood sedimentation and C-reactive protein are indicators of the activity of rheumatic diseases, and when these two items are elevated, it indicates that the rheumatic disease is in an active stage. Anti-streptococcal hemolysin “O” is required for rheumatic fever, rheumatoid arthritis, and rheumatic heart valve disease. Rheumatoid factor can be positive in many rheumatic diseases, such as rheumatoid arthritis, systemic lupus erythematosus, dry syndrome and so on, and is of reference value. However, other tests are needed for a definite diagnosis. Normal rheumatism four generally indicates that there is no rheumatic disease, but not absolutely no, when the rheumatic disease is in the recovery period or the early stage, the rheumatism four may not be elevated. If you have any discomfort or abnormal rheumatism four indexes, we suggest that you go to the hospital in time to find out the cause and follow the doctor’s instructions for treatment.
