Epidermal Antibodies

Also known as: Pemphigus; Pemphigoid; Skin

Immunofluorescence testing plays an important role in the diagnosis of several autoimmune skin diseases. The blistering skin diseases where IIF is used are:

  • Pemphigus Vulgaris (PV)
    Serum antibodies directed against the cell surface of epidermal keratinocytes are found in 90% of patients with Pemphigus and correlate with disease activity.
  • Bullous Pemphigoid
    Serum antibodies directed against the basement membrane are present in 70% of patients. Antibody levels do not reflect disease activity and antibody tends to persist even following successful therapy. Antibodies are uncommon in normal individuals or in other skin diseases.
