FISH Study: DDIT3 (12q13.3) (For Formalin-Fixed Paraffin-Embedded Tissue) (FFPE)

Additional Information:

UFHPL Test #: 30150
UFHPL Epic order code: LAB5851

CPT Code(s):

  • 88367 x 2 (computer-assisted)
  • 88377x 2 (manual)

Specimen Requirements:

  • Formalin-fixed, paraffin-embedded tissues
  • FFPE-isolated nuclei
  • De-paraffinated, four-micron, slide-mounted tissue sections

The identification of tissues/cells to be targeted and DNA probe selection is the responsibility of the requesting or submitting parties.

Tissue sections and tissues utilized to obtain nuclei isolated from paraffin blocks submitted for interphase FISH analysis must include concurrent evaluation by qualified individuals utilizing additional non-FISH morphometric features to ensure that the requested FISH tests are applied to the appropriate tissues/cells.

Use:

This test is used to diagnose myxoid/round cell liposarcoma by detecting a neoplastic association with gene rearrangement.

Methodology:

Interphase nuclei fluorescence in-situ hybridization (FISH) break-apart analyses; previous or concurrent conventional cytogenetic workup recommended (where possible)

Reported:

5 – 14 days

Reference Values:

By report; interpretive
