The technology can uniquely identify a person by analyzing the antibodies in body fluids. A unique, individual set of antibodies, called individual specific autoantibodies (ISA), is found in blood, serum, saliva, urine, semen, perspiration, tears, and body tissues, and the antibodies are not affected by illness, medication, or food/drug intake.
Autoantibody testing: Many autoimmune diseases are characterized by the presence of autoantibodies. Blood tests can identify these antibodies, which are directed against the body's own tissues. [66] For example, antinuclear antibody (ANA) testing is commonly used in the diagnosis of systemic lupus erythematosus and other autoimmune diseases.
Each disorder is listed with the primary organ or body part that it affects and the associated autoantibodies that are typically found in people diagnosed with the condition. Each disorder is also categorized by its acceptance as an autoimmune condition into four levels: confirmed, probable, possible, and uncertain.
In systemic lupus there are autoantibodies to DNA, which cannot evoke a T cell response, and limited evidence for T cell responses implicates nucleoprotein antigens. In Celiac disease there are autoantibodies to tissue transglutaminase but the T cell response is to the foreign protein gliadin.

An antibody is made up of two heavy chains and two light chains. The unique variable region allows an antibody to recognize its matching antigen. [73] A B cell identifies pathogens when antibodies on its surface bind to a specific foreign antigen. [74] This antigen/antibody complex is taken up by the B cell and processed by proteolysis into ...
This is generally due to an increase in immunoglobulin antibodies that activate thyroid-stimulating hormone receptor. [42] Like Hashimoto's thyroiditis, Graves' disease is qualified as an autoimmune thyroid disease. The epigenetic processes involved in Hashimoto's thyroiditis are also involved in Graves' disease.
Each antibody binds to a specific antigen in a highly specific interaction analogous to a lock and key.. An antibody (Ab) or immunoglobulin (Ig) is a large, Y-shaped protein belonging to the immunoglobulin superfamily which is used by the immune system to identify and neutralize antigens such as bacteria and viruses, including those that cause disease.
