Please send the most viable-appearing portion of the specimen

Necrotic tissue and blood in the specimen hinder the growth of the viable cells in culture.

  • For chromosomes, please send 1 cm square tissue when possible.
  • For FISH on paraffin blocks, please send the entire block and a Hematoxylin and Eosin (H&E) stained slide, or 10 unstained 4 micron formalin fixed paraffin-embedded tissue sections on electrostatically charged slides containing representative tumor.

For FISH on touch-prep, please make a fresh cut of the fresh or frozen lymph node. Gently touch the fresh cut surface (several times) to the center of the clean slide. Label the slides with the case identifiers. Allow the slide to air-dry. Place in a covered container to prevent damage to the specimen side of the slide.

Timely delivery/notification is essential. Please call for all incoming specimens (917 328 011).
