Imaging examination: such as CT of small joints, nuclear magnetic examination and ultrasound examination, etc., which can judge and diagnose the lesions of joints and spine. 2. Serologic examination: such as blood sedimentation, C-reactive protein and blood sedimentation, etc., can determine whether the patient is in the active stage of the disease. 3. Rheumatoid joint-related antibodies: such as rheumatoid factor, anti-cyclic citrullinated peptide antibody, anti-keratin antibody and anti-perinuclear factor, etc., which can determine the treatment and control the development of the disease. It is recommended that the patient should consult the doctor in time and choose the appropriate items for examination under the doctor’s guidance.
