Dr. KennedyAn antinuclear antibody is directed against structures within the nucleus of the cell. Antinuclear antibodies (ANAs) are found in people whose immune system is predisposed to cause inflammation against their own body tissues. Antibodies that are directed against one’s own tissues are referred to as autoantibodies. The propensity for the immune system to work against its own body is referred to as autoimmunity. A positive test for ANAs indicates the possible presence of autoimmunity. A few examples of such disease are: lupus, rheumatoid arthritis, celiac, multiple sclerosis, and diabetes type 1. Three are 32 disease states which are known to be autoimmune and another 19 which are suspected. to be autoimmune.
