Serum IgG basement membrane zone antibodies localizing to the epidermal side of split skin substrate in bullous pemphigoid by IIF microscopy
Linear IgG antibody staining on the epidermal side of basement membrane zone-split skin substrate characteristic of bullous pemphigoid. This pattern is also referred to as "staining the roof of the blister."
