Ordering RecommendationRecommendations when to order or not order the test. May include related or preferred tests.
Use to assess and monitor positive IgA basement membrane zone antibodies, including epidermal (roof) pattern, dermal (floor) pattern, and combined on split skin substrate in patients with linear IgA disease, including linear IgA bullous dermatosis and chronic bullous disease of childhood, IgA variant epidermolysis bullosa acquisita (EBA), and overlap expression in pemphigoid with IgG basement membrane zone antibodies. Testing should be clinically supported and/or correlated with concurrent Cutaneous Direct Immunofluorescence, Biopsy (0092572).
Consider ordering concurrently with Epithelial Basement Membrane Zone Antibody IgG (0092056), Bullous Pemphigoid Antigens (180 kDa and 230 kDa), IgG (0092566), and Collagen Type VII Antibody IgG by ELISA (2010905); alternatively order Basement Membrane Zone Antibody Panel (3001410) or Immunobullous Disease Panel, Epithelial (3001409).
For initial linear IgA disease diagnosis, Basement Membrane Zone Antibody Panel (3001410) or Immunobullous Disease Panel, Epithelial (3001409) is preferred.
Reference IntervalNormal range/expected value(s) for a specific disease state. May also include abnormal ranges.
