Ordering Recommendation

Use to assess and monitor cell surface antibodies in patients with IgG pemphigus variants with normal IgG desmoglein 1 and IgG desmoglein 3 antibody levels. Testing should be correlated initially with concurrent Direct Immunofluorescence, Tissue Biopsy (Cutaneous, Mucosal, Epithelial) (0092572). Serum Pemphigus Antibody Panel, IgG (0090650) has increased diagnostic sensitivity and specificity when testing for pemphigus. For comprehensive testing, consider ordering the Immunobullous Disease Antibody Panel (3001409).

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