DIF stands for direct immunofluorescence. It is a test that pathologists perform to look for specific proteins in a tissue sample. Unlike most tissue samples, which are examined using normal light, DIF tissue samples are examined using fluorescent light. This makes it easier for pathologists to see exactly where in the tissue sample the proteins …
