Antinuclear screening is a laboratory blood test for antinuclear antibodies, which are antibodies that can bind to components of the cell nucleus and nearby cellular structures.
Antibodies to glutamate decarboxylase are autoantibodies against the 65-kilodalton isoform of the enzyme glutamate decarboxylase, which is involved in the synthesis of gamma-aminobutyric acid in nervous tissue and is simultaneously an important autoantigen of pancreatic islet cells.
In modern routine medicine, the analysis called "anti-bradykinin antibodies" is not included as a standard diagnostic test for a patient in the main international diagnostic algorithms for bradykinin angioedema and hereditary angioedema.
In modern rheumatology, nephrology and clinical immunology, the term "cytoplasmic antibodies" most often refers to antineutrophil cytoplasmic antibodies - autoantibodies directed against components of neutrophil granules.
When people talk about antibodies to pancreatic beta cells in everyday life or in clinical practice, they usually mean not just one test, but a group of islet autoantibodies directed against the antigens of insulin-producing cells.
Antibodies to beta-2-glycoprotein 1 are autoantibodies, meaning they are antibodies against the body's own structures. In this case, the target is beta-2-glycoprotein 1, a plasma protein associated with phospholipid-binding complexes.
