Immunofluorescence in Dermatopathology

Immunofluorescence is a laboratory technique used in dermatopathology to examine skin samples under a microscope. It helps identify specific proteins or antibodies by tagging them with fluorescent dyes. When exposed to UV light, these dyes emit bright colors that reveal patterns of antibody binding, which can indicate autoimmune skin diseases or infections. This method allows doctors to better understand skin conditions, aiding in accurate diagnoses and treatments. Essentially, it provides a visual "map" of immune activity in the skin, helping to differentiate between various skin disorders.
