Cutaneous immunofluorescent microscopy: a practical diagnostic technique.

Cutaneous immunofluorescent microscopy is a relatively new technique for the diagnosis of cutaneous disorders. Its application has been well established in vesiculobullous and connective tissue disorders. With the development of a transport medium for skin biopsy specimens it has become a practical diagnostic technique. In 1974 a laboratory for immunofluorescent microscopy was established in Vancouver and, on the basis of its experience, the indications for, and results of, immunofluorescent studies are reviewed.
