Rheumatism blood test indicators include: routine examination, C-reactive protein, blood sedimentation, uric acid, complement, autoantibodies and so on. 1. Routine examination: such as blood routine, urine routine, stool routine and liver and kidney function, which are essential for the diagnosis of rheumatism. 2. C-reactive protein: this index often increases during the acute stage of rheumatism. 3. Blood sedimentation: the normal clinical value is 0-15mm/h for men and 0-20mm/h for women, which can be elevated if the patient has rheumatism. 4. Uric acid: If the patient has hyperuricemia or gout, the blood uric acid is usually elevated continuously for a long time. 5. Complement: When SLE is active, complement C3 and C4 are decreased. 6. Autoantibodies: the presence of autoantibodies in the patient’s serum is a major feature of rheumatic diseases. For example, anti-nuclear antibody, rheumatoid factor, anti-neutrophil plasma antibody, antiphospholipid antibody, antikeratin antibody spectrum. If the patient has rheumatic diseases, it is recommended to go to the rheumatology and immunology department of the regular hospital in time to improve the examination and diagnosis and treatment under the guidance of specialists.
