What tests are needed for rheumatic diseases?

The main examinations required for rheumatic diseases include the following aspects: 1. Laboratory tests: Blood routine, urine routine, and stool routine to assess basic health status. Serum biochemical tests to evaluate overall metabolic status. Immunological indicator testing to reflect immune status and the degree of inflammatory response. 2. Imaging examinations: X-ray examination to observe joint structural changes, such as joint space narrowing and bone destruction. CT and MRI scans provide more detailed images of joints and soft tissues and can detect early lesions. Ultrasound examination allows real-time observation of dynamic changes in joints and soft tissues and is valuable for diagnosing conditions such as joint effusion and synovitis. 3. Joint fluid analysis: Aspiration and laboratory testing of joint fluid to analyze cells, proteins, and biochemical components, helping to determine the type and severity of arthritis. 4. Physical examination: Observing the joints, muscles, and skin for abnormal findings such as redness, swelling, tenderness, or deformity.
