Gastric IgG IgA

IgG is human, the main antibody in serum, accounting for about 75% of the total amount of IG in adult serum. IgG in serum is about 50% of total systemic IgG. IgG is the main anti-infective antibody, most antibacterial, anti-toxic and Antiviral antibodies belong to IgG class, and many autoantibodies, such as antinuclear antibodies and anti-gonadoglobulin antibodies, also belong to IgG class. IgA accounts for 10% to 15% of the total amount of IG in serum, but in exocrine fluids such as tears, saliva, milk and respiratory tract, gastrointestinal tract, genital tract secretions, etc., the content of IgA is high, so it is all over the body. That is, the daily synthesis of IgA can reach 66mg/kg, which is the most secreted globulin in the whole body. IgA in serum is serotype, and IgA in exocrine is secreted. Secretory IgA is the main immunoglobulin in mammalian secretions, and it is extremely important to prevent microbial damage on the mucosal surface. Basic Information Specialist classification: Digestive examination classification: biochemical examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Generally no clinical significance. Normal value: IgG: 0-200mg/L IgA: 0-50mg/L Above normal: When suffering from gastric cancer or atrophic gastritis, the check value may be higher than the normal value. negative: Positive: Tips: Keep your mind and pay attention to your diet. Normal value IgG <200 mg/L. IgA < 50 mg / L. Clinical significance 1, significantly increased: gastric cancer. 2, generally elevated: atrophic gastritis. High results may be diseases: gastric cancer, atrophic gastritis precautions 1. Effect of the ratio of antigen to antibody on turbidity: When the ratio of antigen to antibody is equal, the complex formed and the dissociation are equal. When the antigen content is too large, the formed complex is small and tends to be redissolved, and the reversible reaction is large. When the amount of the antibody is too large, the formed complex is bulky and insoluble, and the reversible reaction is small. Therefore, as a rate of turbidity, the antibody is excessive, which is favorable for the formation of the complex. 2. Quality impact of antiserum: Antiserum as an immune response requires high potency, high specificity and high purity. Inspection process An immunoscattering nephelometry procedure was used. Not suitable for the crowd Inappropriate people: Generally there are no people who are not suitable. Adverse reactions and risks Generally, this examination does not have too many adverse reactions and does not have much influence on the body.
