Clinical Information for Immunodermatology (Serum Testing)

Ordering Recommendation

Use to monitor disease in patients diagnosed with epidermolysis bullosa acquisita (EBA) or bullous lupus erythematosus with increased IgG type VII collagen antibody levels.

For initial diagnosis, including discrimination among various immunobullous diseases, and assessment of disease progression/changes and intermittent monitoring, the Immunobullous Disease Antibody Panel (3001409) or Basement Membrane Zone Antibody Panel (3001410) is preferred.

For more information about components, methodology, and specimen type, see the ARUP Immunobullous Disease Testing Comparison tool.
