Test ID: CIB    
Cutaneous Direct Immunofluorescence Assay (IFA), Varies

Method Description Describes how the test is performed and provides a method-specific reference

Frozen sections of biopsy specimens are brought to ambient temperature, air dried, washed with phosphate-buffered saline (PBS), and then layered with fluorescein isothiocyanate (FITC)-conjugated rabbit antihuman IgG, IgA, IgM, and C3. These slides are incubated in a moist chamber at ambient temperature. The sections are then washed with PBS, mounted in buffered glycerine, and viewed under a fluorescence microscope.(Mysorekar V, Sumathy TK, Shyam Prasad AL. Role of direct immunofluorescence in dermatological disorders. Indian Dermatol Online J. 2015;6(3):172-180)
