•Monitor disease in patient with pemphigoid or epidermolysis bullosa acquisita who has positive IgG BMZ antibodies by indirect immunofluorescence, either epidermal (roof) pattern or dermal (floor) pattern, on split skin substrate.
•May use to screen for pemphigoid and other immunobullous diseases; however, this test has decreased sensitivity and specificity when compared to the panel tests for pemphigus antibodies (0090650) or pemphigoid antibodies (0092001) and will not detect IgA BMZ antibodies.
