What are the five tests for rheumatism?

Rheumatology tests refer to inflammatory markers C-reactive protein and erythrocyte sedimentation, as well as rheumatoid factor, anti-O (ASO) and uric acid tests. After these preliminary screening, we can easily determine which type of rheumatism the patient belongs to. For example, the patient has symmetrical joints in both hands, swelling and pain, accompanied by clinical manifestations of morning stiffness. At this time, check the inflammatory indicators ESR, C-reactive protein significantly increased, and at the same time showed a high titer of rheumatoid factor positive, we consider that the patient has a greater possibility of rheumatoid arthritis. However, if a single joint pain as the main clinical manifestation, check the blood uric acid is significantly increased, we consider that the patient has a greater possibility of gout arthritis.
