Clinical Information for Immunodermatology (Serum Testing)

Ordering Recommendation

Use to assess and monitor IgA pemphigus or other nonclassical pemphigus subtypes with both IgA and IgG cell surface antibodies. Testing should be correlated with concurrent Direct Immunofluorescence, Tissue Biopsy (Cutaneous, Mucosal, Epithelial) (0092572).

Consider ordering concurrently with serum Pemphigus Antibody Panel, IgG (0090650) if other types of pemphigus are diagnostic considerations, including intercellular IgG/IgA dermatosis. Alternatively, consider ordering the serum Immunobullous Disease Antibody Panel (3001409).

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
Collect

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.

Remarks

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.

Stability

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

Methodology

Semi-Quantitative Indirect Immunofluorescence (IIF)

Performed

Varies

Reported

Compliance Category

Performed by non-ARUP Laboratory

Note

The methodology is indirect immunofluorescence (IIF) of serum on substrates with known epidermal (epithelial) cell surface desmosomal antigens (both intact human skin and monkey esophagus substrate). For specimens less than 0.5 mL, call the Immunodermatology Laboratory at 801-581-7139.
