The method detects by precipitation: when a soluble antigen (Ag) is brought in contact with the corresponding antibody, precipitation occurs, which may be visible with the naked eye or microscope. [citation needed] Immunofixation first separates antibodies in a mixture as a function of their specific electrophoretic mobility. For the purpose of ...
Serum protein electrophoresis or immunofixation is positive in 67-100% of cases, while urine protein electrophoresis or immunofixation is positive in 50-100% of cases. [2] Serum free light chain measurement is positive in 100% of cases, evidence that the underlying monoclonal plasma cells secrete free light chains as well as heavy chains.
Hypergammaglobulinemia is a condition that is characterized by the increased levels of a certain immunoglobulin in the blood serum. [1] The name of the disorder refers to an excess of proteins after serum protein electrophoresis (found in the gammaglobulin region).
The water-accessible surface area of an IgG antibody. Immunoglobulin G (IgG) is a type of antibody. Representing approximately 75% of serum antibodies in humans, IgG is the most common type of antibody found in blood circulation. [1] IgG molecules are created and released by plasma B cells. Each IgG antibody has two paratopes.
It is characterized by having high levels of a circulating antibody, immunoglobulin M (IgM), which is made and secreted by the cells involved in the disease. Waldenström macroglobulinemia is an "indolent lymphoma" (i.e., one that tends to grow and spread slowly) and a type of lymphoproliferative disease which shares clinical characteristics ...
The syndrome is caused by antiphospholipid antibodies that target a group of proteins in the body that are associated with phospholipids. These antibodies activate endothelial cells, platelets, and immune cells, ultimately causing a large inflammatory immune response and widespread clotting. [1] CAPS was first described by Ronald Asherson in 1992.
ICD-10 is the 10th revision of the International Classification of Diseases (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. [1]
Alpha-2 macroglobulin may be elevated in children and the elderly. This is seen as a sharp front to the alpha-2 band. AMG is markedly raised (10-fold increase or greater) in association with glomerular protein loss, as in nephrotic syndrome. Due to its large size, AMG cannot pass through glomeruli, while other lower-molecular weight proteins ...
