[Immunohistological investigations and complement analysis in immunological diseases (author's transl)].

Immunohistological techniques and complement analysis are essential methods of investigation in the diagnosis of immunologically induced disease processes today. Immunopathogenesis or participation of immunological reactions in inflammatory processes such as glomerulonephritis, dermatitis, arthritis for example, can be detected through immunohistological demonstration of deposits of immunoglobulin and complement in biopsy material. Numerous antibodies against tissue and infection pathogens can be demonstrated in the serum by indirect immunofluorescence techniques.
