[Possibilities of immunofluorescence in clinico-immunologic diagnosis].

The immunofluorescence still represents the essential method of the proof of antibodies circulating in the serum, which are of clinical interest as diagnostic markers of autoimmune diseases. The consideration of subtypes of antibodies (instance antimitochondrial antibodies) additionally alleviates the differential diagnosis. Newer methods of immunofluorescence, such as the double-immunofluorescence for the proof of antibodies against hormone-producing cells and against motorie end-plates, further the solid phase fluorescence immunoassay and the fluoroimmunocytoadherence will in future increasingly be used. Up to now the possibility was little used to use the antibodies circulating in our patients for the diagnosis of non-immunological diseases and the cell-biological diagnosis.
