Ordering Recommendation

Use to assess and monitor IgG basement membrane zone antibodies in patients with pemphigoid, pemphigoid variants/subtypes, and epidermolysis bullosa acquisita (EBA), especially those with normal relevant IgG BP180, IgG BP230, and IgG type VII collagen antibody levels by ELISAs. Testing should be correlated with concurrent Direct Immunofluorescence, Tissue Biopsy (Cutaneous, Mucosal, Epithelial) (0092572).

For initial pemphigoid or EBA diagnosis, a more comprehensive serum panel is preferred; refer to Immunobullous Disease Antibody Panel (3001409). Pemphigoid Antibody Panel (0092001) and Basement Membrane Zone Antibody Panel (3001410) have an increased diagnostic sensitivity and specificity for pemphigoid and pemphigoid/EBA, respectively.

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

New York DOH Approval Status

This test is New York state approved.

Specimen Required

Patient Preparation

Plain red or serum separator tube (SST).

Specimen Preparation

Transfer 2 mL serum to an ARUP standard transport tube. (Min: 0.5 mL)

Storage/Transport Temperature

Refrigerated: Ambient

Unacceptable Conditions

Hemolyzed or lipemic specimens. Plasma.


As a general rule, serum specimens should be shipped to the laboratory as soon as possible.

Store refrigerated unless shipping promptly (within 2 hours). Transport at ambient temperature to arrive within 7 days. If 7-14 days until received in laboratory, store and ship refrigerated. If greater than 14 days, serum specimens must be stored and shipped frozen.


Ambient: 1 week; Refrigerated: 2 weeks; Frozen: Indefinitely
