Clinical Information for Immunodermatology (Tissue Testing)

Ordering Recommendation

Use with serum immunobullous disease/epithelial antibody testing and separate formalin-fixed tissue histopathology for assessment of pruritic, urticarial, blistering, and/or erosive disorders. Use with separate formalin-fixed tissue histopathology for assessment of inflammatory, immune-mediated cutaneous disease.

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.

New York DOH Approval Status

This test is New York state approved.
