Desmoglein 1 and Desmoglein 3 Antibodies in Pemphigus, IgG
0090649
Ordering Recommendation
•Monitor disease in patient previously diagnosed pemphigus and increased IgG desmoglein 1 and/or 3 antibodies; antibody levels correlate with disease activity. Consider ordering with IgG epithelial cell surface antibody (0090266).
•If used to screen for pemphigus, this test has decreased sensitivity and specificity when compared to the pemphigus antibody panel (0090650).
•For initial diagnosis and monitoring disease, the antibody panel testing for pemphigus (0090650) is preferred; panel components include IgG antibody testing for epithelial cell surface and IgG desmoglein 1 and 3.
•For diagnosing rare types of pemphigus, refer to IgA pemphigus antibody (0092106) and paraneoplastic pemphigus (0092107).
