One of the cardinal properties of the immune system is its ability to recognize and respond to foreign antigens but not to self-antigens. Loss of this self-tolerance, results in immune reactions against ones or autologous antigens. Such reactions are called autoimmunity, and the diseases they cause are called autoimmune diseases. Our ELISAs from this panel are suitable for the diagnosis and therapy monitoring of rheumatic diseases, thrombosis, vasculitis, diabetes and autoimmune diseases of the gastrointestinal tract.
