About this test

Return of Extra Slide and Block – One Stained Slide is a pathology laboratory service that allows patients, clinicians, or healthcare institutions to retrieve previously prepared histopathology materials for further evaluation, second opinions, research purposes, or future medical reference.

In histopathology, tissue samples obtained through biopsy or surgery are processed into paraffin blocks and microscopic slides. A stained slide contains tissue sections that have been treated with special dyes, such as Hematoxylin and Eosin (H&E), allowing pathologists to examine tissue architecture and cellular details under a microscope.

Associated paraffin tissue block (if requested and available)

The returned materials may be used for:
