Measures IgG and IgA antibodies against different tissue antigens that are found from head to toe. These tissues are involved in more than 90 different autoimmune diseases. Detection of antibodies against these antigens at the early stage helps in the prevention and management of many autoimmune disorders since these predictive antibodies can be detected 3-19 years before the development of the clinical stage of an autoimmune disease.
