Approximately half of biopsies of oral conditions that clinically resembled typically DIF-positive vesiculobullous diseases did not yield positive findings on DIF testing.

With the exception of pemphigus vulgaris, DIF is essential for establishing a definitive diagnosis for known DIF-positive diseases.
