[ auto antibodies: a diagnostic tool in systemic diseases]

The auto antibodies constitue an important diagnostic tool in the auto-immune diseases, their rates do not correlat with the activity of the disease except for a little number among them. The interest of the research of the auto-antibodies is objectified in: - the positive diagnosis and the different relationships to the systemic diaseases. - the differential diagnosis of the systemic diseases. - the evolution and the prognosis of these affections according to the title or the type of the auto-antibody. The antinuclear antibodies means all the autoantibodies directed against structures of the nucleus. Ang research of antinuclear antibodies starts with tracking, followed by analysis, to identify all or a part of the recognized antigens. After the definition of the antinuclear antibodies and their different specifications as well as their techniques of detection, we are going to review the main systemic diseases, explaning direct interrelationship with different types of auto-antibody
