Direct Immunofluorescence, Tissue Biopsy (Cutaneous, Mucosal, Epithelial)
Ordering Recommendation
Optimal specimen location and complementary serum testing and/or histopathology examination vary according to disease type. Note that specimen location and transport medium/fixative are different for direct immunofluorescence testing and fixed-tissue histopathology.
Use with serum immunobullous disease/epithelial antibody testing and formalin-fixed tissue histopathology for assessment of pruritic, urticarial, blistering, and/or erosive disorders. Use with formalin-fixed tissue histopathology for assessment of inflammatory, immune-mediated cutaneous disease.
For more information on specimen collection requirements and diseases assessed, see the ARUP Immunobullous Disease Testing Comparison tool.
