Suspected of having sclerosis and don’t know what tests should be done is believed to be something that troubles many people, in order to help alleviate your worries, the following is an introduction to what tests need to be done for sclerosis. Rheumatoid factor: Rheumatoid factor is an antibody produced by the body due to the infection factor (bacteria, virus, etc.) with denatured IgG (an antibody) as the antigen, so it is also called anti-antibody. The common rheumatoid factors are type I gM, IgG IgA and IgE. Rheumatoid factors are commonly found in the human body and play a certain physiological role. Antinuclear antibodies (ANA): Antinuclear antibodies are a general term for a group of autoantibodies that use various components of one’s own eukaryotic cells as target antigens and can react with the nuclei of all animals. They are found mainly in serum, but also in pleural fluid, synovial fluid and urine. Chest fluoroscopy: Fluoroscopy is a direct examination where the patient is placed between an X-ray tube and a fluoroscopic screen. It can do comprehensive dynamic direct observation, such as heart beat, transverse septal activity, gastrointestinal peristalsis, joint activity, etc. Gastric barium meal imaging: barium is a contrast agent that the patient takes orally or by enema, which can make the gastrointestinal tract appear more clearly under X-ray irradiation. X-ray examination of the stomach is based on the use of double contrast contrast method and the comprehensive examination program of mucosal method, filling method and compression method, which is conducive to detecting lesions and improving the diagnosis rate. Protein electrophoresis: In alkaline environment, serum proteins are all cathodically charged and swim toward the anode in the electric field. Because of the difference in isoelectric point and molecular weight of each protein, small molecular weight and more cathodic charge swim fastest; those with large molecular weight and less cathodic charge swim slower. After electrophoresis, starting from the anode, the five zones are albumin, a1 globulin, a2 globulin, β globulin and γ globulin in order. Barium duodenal imaging: The imaging method can show the morphology of the duodenum and is valuable for the observation of organic lesions of the duodenum, especially for the diagnosis of obstructive jaundice and lesions around the jugular abdomen.
