The direct IHC method is still commonly used today for the detection of immunoglobulins (antibodies) and complement proteins in frozen sections of tissues like skin and kidney biopsies. This application is central to diagnosing autoimmune and immune complex-mediated diseases. In conditions such as lupus nephritis, membranous glomerulonephritis, or certain blistering skin diseases (e.g., pemphigus), the patient's own antibodies and complement proteins are deposited in the tissues. A direct immunofluorescence (DIF) test, which is a direct method using fluorochrome-labeled antibodies against human IgG, IgA, IgM, or complement, is performed on fresh frozen tissue. The simplicity and speed of the direct method are advantageous here, and the high concentration of the target proteins often negates the need for signal amplification. The direct method provides clear, specific staining patterns that are diagnostic for these conditions.
