Rheumatology and immunity indexes are examined by blood sampling and laboratory tests. Routine tests include blood sedimentation, C-reactive protein, complement and autoantibodies, and autoantibody tests include antinuclear antibody, rheumatoid factor and antiphospholipid antibody.
1. Routine tests are used to diagnose the disease and determine the activity of the disease, commonly used indicators are blood sedimentation, C-reactive protein, complement, etc. For example, rheumatoid arthritis has elevated blood sedimentation and C-reactive protein, and systemic lupus erythematosus has decreased complement C3 and C4.
2. The presence of autoantibodies in serum is a major feature of rheumatic immune diseases, and the detection of autoantibodies can be used for diagnosis and differential diagnosis. Antinuclear antibodies can be divided into anti-histone, anti-non-histone, anti-DNA and anti-nucleolus antibodies, and the positivity rate of rheumatoid factor in rheumatoid arthritis is 80%, and the antiphospholipid antibodies include lupus anticoagulant, anticardiolipin antibody and anti-beta 2GPI antibody.
Rheumatoid immunity index test is recommended to the hospital, under the guidance of a professional doctor for examination.
