IgG Antibody Assessment Panels

IgG

IgG antibodies represent the most prevalent class found in the blood. It is produced after reimmunization, or secondary response to antigen. It is the primary mediator of the memory immune response. Often involved in Type III delayed hypersensitivity reactions, IgG forms an immune complex with the allergen. This antibody/antigen complex activates complement (a group of small proteins found circulating in the blood stream that are involved in the release of inflammatory mediators), and enhances phagocytosis by opsonization. The inflammatory process is gradual and may take anywhere from several hours to several days, which is why this type of reaction is termed, delayed. Although immune cells called macrophages dispose of these immune complexes immediately, they only have a finite capacity to do so. Excess antigen may saturate the macrophages capacity resulting in the prolonged circulation of complexes and their deposition into the body tissues. Depending on which tissues are involved, it is thought that these complexes may be implicated in many different conditions/symptoms.

*There are several subclasses of IgG; IgG1, 2, 3, and 4. US BioTek assays for all 4 subclasses and reports this as the total IgG antibody level scored for each antigen.
