Bullous Pemphigoid, BP180 and BP230, IgG Antibodies, Serum
Use
This test is used as an initial screening tool for the diagnosis of bullous pemphigoid and its variants. It is performed using the Enzyme-Linked Immunosorbent Assay (ELISA) to detect serum IgG antibodies against BP180 and BP230 antigens, which are common in patients with bullous pemphigoid. The test helps in complementing the standard serum test of indirect immunofluorescence using primate esophagus substrate and primate salt-split skin substrate.
Special Instructions
The performance of the assay in pediatric patients and on matrices other than serum has not been established. As with other diagnostic procedures, results are only an aid to diagnosis and should not be taken alone as conclusive evidence of the disease.
Limitations
The assay is not validated for use on specimen types other than serum or on pediatric patients. It serves as an aid in diagnosis and should not be interpreted as conclusive on its own. False positives can occur, as seen with 11% of patients with other autoimmune blistering disorders showing BP180 autoantibodies.
