The methodology is indirect immunofluorescence (IFA) of patient serum on substrates from rodents including mouse heart, liver, bladder and rat bladder to detect characteristic staining: intercalated discs in heart; portal tracts in liver; and simple columnar epithelium cell surface and basement membrane zone in bladders.
Characteristic staining of two or more substrate tissues is required for diagnosis. Staining must include bladder epithelial cell surface staining.
